1) active transport - moves up against a concentration gradient, requires a carrier.
2) diffusion ,simple - moves down a concentration gradient.
3) diffusion, osmosis - moves small or lipid-soluble solutes through the membrane.
4) Exocytosis - used to eject waste and to secrete cell products.
5) facilitated diffusion - membrane transport using channels or carrier proteins that doesnot require ATP.
6) filtration - driven by hydrostatic pressure.
7) phagocytosis - engulfment processes that require ATP.
8) pinocytosis - a means of bringing a fairly large particle into the cell.
9) receptor-mediated endocytosis - examples of vesicular transport.
