Cell
- 1. Cell Basic unit for living beings Bounded by a plasma membrane. Also presents cytoplasm. In eukaryotic cells one or two nucleous can be found In most of the plants, mushrooms and bacteria there is a cell wall outside of the plasma membrane Cell Theory states the cell as the basic structural and fuctional unit of all living organisms, and also for origin
