fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and uses the cells apparatus for reproduction. Fungi – it is a multi-celled living organism. Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 2) Identify common illnesses and infections caused by bacteria‚ viruses‚ fungi and parasites.

KEY ROLES OF CELL DIVISION The ability of organisms to reproduce best distinguishes living things from nonliving matter. The continuity of life is based on reproduction of cells‚ or cell division. In unicellular organisms like amoeba‚ division of one cell reproduces the entire organism. Multicellular organisms depend on cell division for: — Development from a fertilized cell — Growth — Repair Cell division is an integral part of the cell

Cell division is the growth process of many living organisms such as amoebas‚ plants‚ and human skin cells. Based on an ideal situation in which no cells die and no by-products are produced‚ the number of cells present at a given time follows

Model organisms are organisms used for research. They are alive‚ non-human species used for the purpose of studying different human diseases or other related experiments in which human testing would be considered either unsafe or unethical. Scientists study a particular biological phenomenon on a model organism and try to relate their findings to other types of organisms that are more difficult to study. As an example‚ 60% of human disease genes have an equivalent in the fruit fly and nematode worm
