what are the 3 types of passive transport
simple diffusion, osmosis, facilitated diffusion
what are the two types of active transport
vesicular transport, active transport
where does simple diffusion and vesicular transport occur
channel protein
describe osmosis
movement of water molecules only osmosis stops when water molecules are equal on both sides of the SPM passive transport
compare facilitated and simple diffusion
facilitated - through carrier protein simple - through channel protein
what is exocytosis
when substances are transported out of the cell through a vesicle
what is endocytosis
when substances are taken into the cell, enclosed in a vesicle
what does phagocytosis transport
solids
what does pinocytosis transport
liquids
