Document Summary

Bacteria are small one celled moneran"s, like warm, dark and moist conditions. Bacteria is reproduced asexually through a process called binary fission. Asexual reproduction: is reproduction of a living thing from only one parent. One main chromosome makes a copy of itself and then divides in 2. 2 parents provide genetic material in order to produce offspring. Thick celled structure that forms inside the cell. Allows bacteria to survive for a long time. With stands boiling, freezing, and extremely dry conditions. Encloses all nuclear material and some cytoplasm. Parasites: organisms that feed off of living things. Saprophytes: organisms that feed off of dead materials. Decomposers: get food from breaking down matter into simple chemicals. Anaerobes: don"t need oxygen to survive but some die when there is oxygen *eg soil. Harmful: can cause diseases, communicable disease: passed down from one organism to another.
