1.  INTRODUCTION - OVERVIEW -  Biology as a science deals with the origin, history, process, and physical characteristics, of plants and animals: it includes botany,  and zoology. A study of biology includes the study of the chemical basis of living organisms, DNA.  Other related sciences include microbiology and organic chemistry.  See the "Online Biology Book"  an excellent reference!! The main difference between a lifeless clump of chemicals, and a living life form, composed of the same chemicals, is;  Information and access to an energy source.  The word science comes from a Latin word scientica, which means knowledge, or information.   Science is a process of systematically gathering detailed information and gaining exact knowledge.  That vital  information includes; how the basic elements are organized and how they utilize energy.   We do not know all the "life" information secrets but we are learning more every day.  

The three biological life cycles, are; Zygotic meiosis, Sporic meiosis, and Gametic meiosis,

Amoeba - one basic life form.

Amoebas (and there are many different kinds) feed by phagocytosis (the engulfing and ingesting of foreign particles or waste matter by phagocytes)--they flow around their prey (usually a smaller cell) and engulf it. Organism that eat other organisms are usually called "consumers".  The amoeba's cell membrane then fuses with itself, trapping the prey in a "food vacuole" where it will be digested.

Famous scientist quote:
"Those engaged in the arts and sciences, Most Gracious Emperor Charles, find many serious obstacles to the exact study and successful application of them.  In the first place, no slight inconvenience results from too great separation beween branches of study which serve for the perfection of one art."  Andreas Vesalius (1514 - 1564) wrote "The Anatomy of the Human Body" published in 1543.

Overview of biology   

Reference: http://en.wikipedia.org/wiki/Biology

Biologists study life over a wide range of scales:

at the atomic and molecular scale, through molecular biologybiochemistry and genetics (study of organic molecules, their structures, functions and interactions)

at the cellular scale, through cell biology

at the multicellular scale, through physiologyanatomy and histology

at the level of the development or ontogeny of an individual organism, through developmental biology

at the level of the population of organisms, in population genetics and interactions between them in ethology (behavior and adaptability)

on the multi-species scale of lineages, through systematics (comparison and classification of living organisms)

to the top of the scale in ecology (study of ecosystems, interactions between living organisms and their environment) and evolutionary biology

to Xenobiology (or exobiology, or astrobiology), a mostly speculative field that considers the possibility, and possible nature, of extraterrestrial life.

Major branches of biology

Aerobiology -- Anatomy -- Astrobiology -- Biochemistry -- Bionics -- Biogeography -- Bioinformatics -- Biophysics-- Biotechnology -- Botany -- Cell biology -- Chorology -- Cladistics --Cryptozoology -- Cytology -- Developmental biology -- Disease (Genetic diseasesInfectious diseases) -- Ecology (Theoretical ecologySymbiologyAutecologySynecology)-- Ethology --Entomology-- Evolution (Evolutionary biology) -- Evolutionary developmental biology ("Evo-devo" or Evolution of Development) -- Freshwater biology -- Genetics (Population geneticsQuantitative geneticsGenomicsProteomics) -- Histology -- Immunology -- Infectious diseases -- Pathology -- Epidemiology -- Limnology -- Marine biology -- Microbiology (Bacteriology) -- Molecular Biology -- Morphology -- Mycology / Lichenology --- Myrmecology --- Neuroscience (NeuroanatomyNeurophysiologySystems neuroscienceBiological psychologyPsychiatryPsychopharmacologyBehavioral scienceNeuroethologyPsychophysicsComputational neuroscienceCognitive science)-- Oncology (the study of cancer) -- Ontogeny -- Paleontology (PalaeobotanyPalaezoology)-- Phycology (Algology) -- Phylogeny (PhylogeneticsPhylogeography) -- Physiology -- Phytopathology -- Structural biology -- Taxonomy -- Toxicology (the study of poisons and pollution) -- Virology -- Xenobiology -- Zoology

As you can see there are far more than 25 branches of biology.  There are also several related disciplines.

Related disciplines

Medicine -- Physical anthropology

Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. Together, they study life over a wide range of scales:

and speculatively through xenobiology at the level of life beyond the Earth.

2.  THE SCIENTIFIC METHOD - The scientific method consists of stating a problem then; (1) make observations, (2) formulate a hypothesis, (3) design an experiment, collect and interpret the data, consult prior knowledge, and (4) reach conclusions.  

A good experiment has a large sample; it is controlled so that only one variable is assessed, it  is placebo controlled, and it is conducted in a double blind manner.  Scientific discovery is not always as well planned as the scientific method may seem to suggest.  Sometimes new knowledge comes simply from being in the right place at the right time or from being particularly aware of the unusual.  The opposite of the scientific method (and its organized planning) is discovery by "accident".

A hypothesis is a guess as to why something happens. Observations lead to questions regarding the event. Why is the sky blue? How does gravity affect falling objects? In attempting to answer a question about the nature of the world, a scientist will form a hypothesis (or a guess) regarding the question's answer.  Experiments, data gathering and study will then help the scientist to reach a conclusion.

3.  WATER - Living things are built almost entirely of organic compounds containing carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, and water.  Water is vital to life because it forms the basis of many body fluids, it is imbibed by structures such as seeds, and it controls temperature regulation.

Famous scientist quote:
"When on board H.M.S.

5.  PROTEIN - A study of life starts with chemistry.  All life forms are composed of basic chemical elements.  Atomic elements prefer to exist as molecules.  Earth life thrives on water.  Common water.  The human body for example is about 3/5ths water.  Life is built up from some very common materials.  There is one substance though that is more complicated and vital to life.  It is protein.  A Dutch biochemist, named Mulder, first used the word "protein" in 1838.  He got the word form a Greek word meaning "holding first place."  A protein molecule is quite large compared to fat or sugar molecules.  Although proteins are complicated they consist the elements of carbon, hydrogen, oxygen, nitrogen and sulphur.  Some parts of the human body contain more than other parts but it exists is some amount in all parts of the body and it is vital for life to exist.  There is no living organism that does not contain protein.  Viruses for example contain a complicated type of protein called nucleoprotein.  Nucleoprotein contains a type of substance called nucleic acid  in association with the protein.  When proteins are exposed to an acid the protein breaks apart into smaller molecules.  These smaller molecules are called amino-acids.  Millions of different proteins can be formed from the combinations of different amino-acid molecules.  Some common proteins are:  keratin, fibroin, collagen, and the important and numerous globular proteins.

6.  ENZYMES - The word enzyme was first used in 1878 and comes from two Greek words meaning , "in yeast."  All enzymes are globular proteins.  Enzymes control body chemistry.  The enzymes of the human body work by means of surface catalysis (http://www.encyclopedia.com/).  That is the surface of the enzyme enables other molecules to react in a manner they would not without the surface of the enzyme present.  The enzyme being the catalyst is not changed in any manner from the action of the protein.  The human body contains only a small quantity of enzymes but even this small quantity is sufficient.  They are important to many functions including food digestion.   Click HERE(http://www.agron.missouri.edu/enzyme.html) for the enzyme database.  For an explanation of what an enzyme is click here http://www.purchon.com/biology/enzymes.htm

7.  CELL STRUCTURE & FUNCTIONS -  Most cells are small and can be seen only with a microscope.  Some, however such as egg cells of birds, can be seen with the naked eye.  Others, like nerve cells, may be very small in some of their dimensions, but extremely long; a single human nerve cell may be as much as 3 or 4 feet long, and anImage from http://www.biosci.uga.edu/elephant's nerve cell may be even longer.  To say that cells are generally small is not saying much, however, because even among microscopic cells there is a wide range in size. Biologists took it for granted that cells are bounded by a membrane - the plasma membrane, as it is often called.  It had been known for al long time that lipids  (http://www.encyclopedia.com/)  and many substances soluble in lipids move with relative ease between the cell and the surrounding medium.  From this it was deduced that the outer boundary of the cell, the cell membrane, must contain        (        NOTE:  Cell image from http://www.biosci.uga.edu/          )   lipids, and that fat-soluble substances could move across the membrane by being dissolved in it.  The cell membrane is not simply an envelope giving mechanical strength and shape and some protection to the cell, though these functions are important.  It is an active component of the living cell and playing a complex  and dynamic roll in life processes.  It regulates the traffic in materials between the precisely ordered interior of the cell and essentially unfavorable and potentially disruptive outer environment.    The processes include diffusion,  (http://www.encyclopedia.com/) osmosis,  (http://www.encyclopedia.com/) and phagocytosis.   (http://www.encyclopedia.com/) Phagocytosis is when the material engulfed is in the form of large particles or chunks of matter.  Usually portions of the cell flow around the material, enclosing it within a chamber.    When the engulfed material is liquid or consists of very small particles, the process is often termed pinocytosis.   (http://www.encyclopedia.com/)  Indicating a slight difference in the way the material is engulfed.

Ligustrum Leaf Cross Section

Evergreen ligustrum (often called privet) shrubs and trees thrive throughout the state of Florida. They are widely used as landscape shrubs, hedges, and specimen trees. Many species and cultivars are available with a diversity of leaf colors, leaf forms, and growth habits. All selections are tolerant of heavy pruning, which makes them suited for clipped hedges. Because of a rapid growth rate, many require pruning to maintain them within bounds. The white flowers are attractive during late spring and early summer. However, the pungent odor may be objectionable.

 8.  NUCLEUS -  Within most cells (though not of bacteria and blue-green algae), the largest and one of the most conspicuous structural areas is the nucleus, the control center of the cell.  The nucleus plays the central role in cellular reproduction, the process whereby a single cell undergoes cell division and forms two new cells.  The nucleus directs the metabolic activities of the living cell and guides the life of the cell as long as it lives.  Biologists attach so much importance to the nucleus that they even have a special name, cytoplasm, for all the protoplasm other than the nucleus; the nucleus and the cytoplasm  can thus be thought of as the two major subdivisions of protoplasm.

9.  CHROMOSOMES - The chromosomes are elongate, threadlike bodies clearly visible only when the cell in undergoing division.  They are composed of nucleic acid and protein.  The chromosomes bear, apparently in linear arrangement, the basic units of heredity, called genes.  It is the genes that determine the characteristics of cells, as they  are passed form generation to generation, and that act as the units of control  in the day-to-day activities of living cells.  They are the code units of the transmission of bits of information from parent to offspring, and for the determination of the enzymes that so precisely regulate the myriad interdependent chemical reactions of life.

DNA in a Nutshell!  

DNA - From the Beginning

Primer on Molecular Genetics from the U.S. Department of Energy

NEW! FREE Software (pDRAW32) to draw DNA Analysis Charts    http://www.acaclone.com/   pDraw32 DOWNLOAD software - pDRAW32 lets you enter a DNA name and coordinates for genetic elements, such as genes, to be plotted on your DNA plots.  pDRAW32 lets you "clone" fragments of DNA generated by virtual digestion with restriction enzymes and optionally blunted at one or both ends. Up to 3 fragments may be cloned at a time (can you replicate that in the lab?). Each fragment may be inverted relative to its original orientation. Genetic elements contained in the cloned fragments are transferred to the cloned DNA. (...and much more!)

We found an excellent Genetics tutorial: Morgan.  You will have to register to view it but it is free. http://morgan.rutgers.edu/MorganWebFrames/htmldocs/register.html

11.  VIRUS - Viruses are infectious particles that consist of a DNA or RNA molecule packaged in a protein capsid.  A virus can multiply only inside a host cell, whose genetic mechanisms it subverts for its own reproduction.  Both the structure of the virus and its mode of replication differ widely between viruses.  The usual outcome of a viral infection is the lysis (destruction) of the infected cell, with the release of viral particles.  Some viruses, however, can instead become integrated into the host chromosome, where their genes are replicated along with those of the host cell.  Because viruses sometimes carry host DNA sequences from one species to another, they make possible an occasional mixing of different gene pools during their evolution.  Virulent viruses usually kill the cells they infect.  Other viruses, although also often able to kill cells, frequently have a more subtle effect.  These viruses are called temperate.  Virus infected bacteria which appear un-infected but have the hereditary ability to produce phage, are called lysogenic.  (Phage - indicating something that devours another)  The lambda genome has two set of genes, one controlling lytic growth, the other lysogenic growth.  Upon infection, genes promoting both lytic growth and lysogenic integration are expressed.  Which pathway succeeds is determined by the competing action of these early gene products and by the influence of host factors.  The lambda phage is a well studied temperate phage which can grow in synchrony with its host (E.coli) in its lysogenic phase, or go into a lytic phase, when its genome is replicated many times by a rolling circle mechanism.  The lytic cycle is that part of the life cycle of a temperate phage in which it multiplies rapidly, destroying its host and releasing many copies into the medium.  The pathway genes in the lambda immunity region are:  cro, Or, and cI.  The lambda system provides one of the best studied examples of a genetic switch.  Two back-to-back promoters in the region of cI and cro control the genetic switch.  When cI is present it activates its own synthesis and blocks transcription of cro.  When cI is inactivated, transcription of cro can occur, resulting in the lytic cycle.  The cI protein combines with the operator, Or.  Transcription is the process by which an RNA polymerase produces single-stranded RNA complementary to one strand of DNA or, rarely RNA.  Polymerase are enzymes producing a polynucleotide sequence, complementary to a pre-existing template polynucleotide.  DNA polymerase requires a primer from which to start polymerization whereas RNA polymerase does not.  Polymerization is the combination of several molecules to form a more complex molecule, usually by addition or a condensation process.  It is sometimes a reversible process.

Famous scientist quote:
"The sciences gain by mutual support.  When, as the result of my first communications on the fermentations in 1857-1858, it appeared that the ferments, properly so-called, are living beings, that the germs of microscopic organisms abound in the surface of all objects, in th air and in water; that the theory of spontaneous generation is chimerical; ..." Louis Pasteur (1822 - 1895)  developed a method of inoculation of cattle for anthrax proving the efficacy of vaccinations.

ZOOLOGY

What is zoology anyway?

The study of animals.

The branch of biology that studies and classifies animals and animal life. It is a branch of biology that is concerned with the scientific study of animals, including their biology, distribution, and identification and including the study of animals - mammals, birds, reptiles, amphibians, fish, insects, spiders, and mollusks (including mussels).

The science and history of the animal kingdom, including its king, the House Fly (Musca maledicta). The father of Zoology was Aristotle, as is universally conceded, but the name of its mother has not come down to us. Two of the science's most illustrious expounders were Buffon and Oliver Goldsmith, from both of whom we learn (L'Histoire generale des animaux and A History of Animated Nature) that the domestic cow sheds its horn every two years.

OK, OK enough of the definitions - now tell me some zoology details.  I want details please.

Famous scientist quote:
"There is only one genus of man and this genus is unique in its order.  Since the [natural] history of man interests us most directly and should stand as the basis of comparison to which we submit the accounts of all other animals, we shall treat it in greater detail."  
Georges Cuvier (1769 - 1832) is the father of comparative anatomy and paleontology, and animal classifications.

Fruits

Definitions of fruit:

  • the ripened reproductive body of a seed plant
  • the consequence of some effort or action; "he lived long enough to see the fruit of his policies"
  • cause to bear fruit
  • yield: an amount of a product
  • bear fruit; "the trees fruited early this year"
    wordnet.princeton.edu/perl/webwn
  • In botany, a fruit is the ripened ovary, together with its seeds, of a flowering plant. In cuisine, when discussing fruit as food, the term usually refers to just those plant fruits that are sweet and fleshy, examples of which would include plum, apple and orange. However, a great many common vegetables, as well as nuts and grains, are the fruit of the plants they come from. ...

FUNGI (Mildews, mushrooms, fungus, etc.

Definitions of Fungi:

  • saprophytic and parasitic organisms that lack chlorophyll and include molds, rusts, mildews, smuts, mushrooms and yeast; singular, fungus.
    www.hcs.ohio-state.edu/mg/manual/glossary.htm
  • Mushrooms.
    www.recipestogo.com/glossary/glossaryF.html
  • (sing. Fungus)-A class of cellular plants, of which Mushrooms, Toadstools, and Moulds, are familiar examples. 77
    www.bartleby.com/11/104.html
  • A group of organisms that lack chlorophyll and obtain nutrients from dead or living organic matter
    www.people.virginia.edu/~sos-iwla/Stream-Study/StreamStudyHomePage/Glossary.HTML
  • Aerobic, multicellular, nonphotosynthetic, heterotrophic microorganisms. The fungi include mushrooms, yeast, molds, and smuts. Most fungi are saprophytes, obtaining their nourishment from dead organic matter. Along with bacteria, fungi are the principal organisms responsible for the decomposition of carbon in the biosphere. Fungi have two ecological advantages over bacteria: (1) they can grow in low moisture areas, and (2) they can grow in low pH environments. ...
    www.nsc.org/ehc/glossary.htm
  • Molds, mildews, yeasts, mushrooms, and puffballs, a group of organisms lacking in chlorophyll (ie, are not photosynthetic) and which are usually non-mobile, filamentous, and multicellular. Some grow in soil, others attach themselves to decaying trees and other plants whence they obtain nutrients. Some are pathogens, others stabilize sewage and digest composted waste.
    www.stpetebeach.org/glossary/f.asp
  • Simple plants, often microscopic, that lack photosynthetic pigment.
