Definition
| 1. A cell is he basic structural and functional unit of living organisms. 2. The activity of an organism depends on both the individual and the collective activities of its cells. 3. The biochemical activities of cells are dictated by the relative number of their specific subcellular structures. 4. Continuity of life from one generation to another has a cellular basis |

|
|
Term
|
Definition
| a series of integral protein molecules in the plasma membranes of adjacent cells fuse together, forming an impermeable junction that encircles the cell |
|
|
Term
|
Definition
| "binding bodies"; mechanical couplings scattered like rivets along the sides of abutting cells that prevent their separation |
|
|
Term

Term
|
Definition
| Cells retain their normal size and shape (same solute/water concentration as inside cells; water moves in and out) |
|
|
Term
|
Definition
| Cells lose water by osmosis and shrink (contains a higher concentration of solutes than are present inside the cells) |
|
|
Term
|
Definition
| Cells take on water by osmosis until they become bloated and burst (contains a lower concentration of solute than are present in cells) |

|
Term
|
Definition
| Vesicular transport processes that eject substances from the cell interior into the extracellular fluid |
|
|
Term
|
