[q]

PASSIVE transport of material for a cell – examples [a]DIFFUSION, OSMOSIS, and FILTRATION .

[q]

DIFFUSION – define[a]This type of transport causes the movement of solute molecules from an area of high concentration to an area of low concentration. (respiratory gases)

[q]

OSMOSIS – define[a]This type of transport causes the movement of a solvent (water) across a semipermeable membrane from an area of high concentration to low concentration.

[q]

ACTIVE TRANSPORT of material for a cell – examples [a]PINOCYTOSIS and PHAGOCYTOSIS and Carrier molecules

[q]

PINOCYTOSIS – define[a]This cellular process encloses dissolved particles (the cell drinks).

[q]

PHAGOCYTOSIS – define[a]This cellular process encloses large, undissolved particles (the cell eats).

[q]

ENDOCYTOSIS – define[a]A processby by which a cell absorbs materials.

[q]

EXOCYTOSIS – define [a]A processby by which a cell expells materials.
