a neucleus (contains DNA that controls what the cell does)
cytoplasm (gel-like substance where most of the chemical reactions happen.)
cell membrane (holds the cell together and controls what goes in and out.)
mitochondria (these are where most of the reactions for resperation take place... respiration releases energy that the cell needs to work).

3 extra things that the plant cell has
1) RIGID CELL WALL (made of cellulose gives support for the cell)
2) LARGE VACUOLE (contains cell sap, a weak soloution of sugar and salts)
3) CHLOROPLASTS (where photosynthesis occurs, they contain a green substance called chlorophyll)

bacteria cells have no neucleus!
bacteria cells are a lot smaller than plant or animal cells and have these features:
1) chromosomal DNA (one long circular chromosone) controls the cells activities and replication. it floats free in the cytoplasm (not in a neucleus)
2) plasmids are small loops of extra DNA that aren't part of the chromosone. plasmids contain genes for things like drug resistance, and can be passed between bacteria.
3) flagellum (plural flagella) is a long hair like structure that rotates to make bacterium move.
4) cell wall the cell is supported by the cell wall.
