An "organism" is an individual form of life, such as plants, animals, protist, bacterium, or fungi. It is a body made up of organs, organelles, or other parts that work together to carry on the various processes of life.

In short, a living thing.

how did early civilisation explain boilogical diversity? early philosiphers believed that the huge variety of different organismes that exist on earth were created by a supreme being (i.e GOD) and that they were immutable (they could change).
 * __History Of Science__**

the process of organising organisms into groups based on predetermined criteria is called a classification. the classification of living things is said to be a strong multilevel classification. Strong, because the scheme gives gives prefictable results. Multilevel because major groupings may be further sibdivided into a smaller, subgroups.
 * __Classification__**

The Criterion we use to assign organisms to groups os the closeness of the evolutionary relationships between memberes of the group. This is useually observed by looking at the number of fetures shared by organisms when we compare them. Features that might be used when looking to group organisms could include : __5 Kingdoms Activity__
 * 1) Physical structures( e.g anatomy of bones, teeth, organs etc)
 * 2) Biochemistry (e.g protien similarities )
 * 3) manner of development
 * 4) Behavioural charactaristics
 * 5) Similarities

__Hierarchies of Organisms__
organisms have the folowing levels of organisation write a definition for each of these levels and give an example for each level. > charged nucleus surrounded by a system of electrons. e.g. oxygen > > properties of the substance and is composed of two or more atoms; a group of > different atoms held together by chemical forces. e.g. H2O > > functioning, consisting of one or more nuclei, cytoplasm, and various > organelles, all surrounded by a semipermeable cell membrane. e.g. Muscle cell > > > matter acting together to perform one or more specific functions in the body. > There are four basic types of tissue: muscle, nerve, epidermal, and connective. >
 * 1) Atoms
 * 2) Molecules
 * 3) Cells
 * 4) Tissues
 * 5) Organs
 * 6) Organ systems
 * 1) Atom: A unit of matter, the smallest unit of an element, having all thecharacteristics of that element and consisting of a dense, central, positively
 * 1) The smallest particle of a substance that retains the chemical and physical
 * 1) The smallest structural unit of an organism that is capable of independent
 * 1) An aggregation of morphologically similar cells and associated intercellular
 * 1) a group of tissue that together preform a specific function e.g. Lungs[[image:http://i01.i.aliimg.com/photo/v0/234626119/Larynx_Heart_and_Lung_organ_anatomical_model.jpg width="357" height="226"]]
 * 2) a group of organs that work together to preform tasks. e.g. respiratory system[[image:http://www2.estrellamountain.edu/faculty/farabee/biobk/humrespsys_1.gif width="509" height="433"]]

Carbohydrates- simple sugars(mono and disaccharides) join together to make comlex carbohhydrates(polyseccharides). - gluucose is a monosaccharide that is the starting chemical of CELLULAR RESPIRATION ( the process by which the energy in carbohydrates is converted to a useable form of energy for a cell.)
 * __Macromolecules__**

- Proteins are made of amino acids joined together to form longer molecules (called protiens.) - Proteins are ised as structural compinents in cells and tissues. - Aslo have a regulatory role in controlling biochemacal reactions i.e. enzymes are biological catalyst.
 * __Protiens__**

- an important component in cellular membranes - a high dencity energy storage product
 * __Lipids__**
 * -** fats and oils

- R.N.A (ribonucleic acid) - "Information storage" molecules - contain the imformation that "codes" for protiens - the information that makes you, you (when mixed with your enviroment and experience). DNA found in nucleus of eukaryotic cells (chromeosomes) and chloroplasts and mitochondria.
 * __Nucleic Acids__**
 * -** D.N.A (deoxyrobonucleic acid)

__**Adaptation**__ 1) give an example of an adaptation and how it helps animal (and its species) to survive. stripes on a tiger which helps it blend in with the undergroath in the jungle to easily hunt its prey.

2)give 3 examples of: a) structural adaptations: turtle shell, ant-eaters snout and long toung so it can get the the ants in the b) behaviour adaptation

3) jack rabbits, bilbys and fennec foxes all live in desert enviroments find a picture of each. what structural feature do they obviously share and how does this adaptation help them to survive in their desert habitats MY GLOSSARY PAGE
