Term
|
Definition
| the constant movement of particles from a region of relatively higher concentration to one of lower concentration |
|
|
Term
|
Definition
| applies specifically to the diffusion of water through a semipermeable membrane. the water molecules move from an area where there are more of them (an area of lower solute concentration) to an area where there are fewer of them (an area of higher concentration). |
|

| describes the bulk movement of materials into the cell |
|
|
Term
|
Definition
1. large particles are engulfed by the plasma membrane and moved into the cell.
2. white blood cells carry out phagocytosis to rid the body of foreign material and dead cells.
3. material taken into a cell is enclosed in a vesicle made from the plasma membrane, and then destroyed by lysosomes. |
