Part 3. |
|
Definition
Tightly coordinated cell functions.
The cell's sub-cellular parts work together in a highly coordinate mechanism. Coordinate action enables high reproduction rate. |

Term
| Cell Membrane (or inner membrane for gram-negative cell) |
|
Definition
| The membrane is composed of phospholipids, hydrophobic proteins, and other molecules. |
|
|
Term
|
Definition
| The membrane prevetns cytoplasmic proteins from leaking out and maintains gradients of ions and nutrients. |

Term
|
Definition
| A rigid structure composed of polysaccharides linked covalently by peptides (peptidogylcan). the cell wall forms a single cage-like molecule that surrounds the cell. |
