1. Pinocytosis Cell drinking
2. Phagocytosis Cell eating
3. Exocytosis release of substances outside a cell by the fusion of a vesicle with the
membrane.
4. Endocytosis process by which a cell takes material into the cell by infolding of the
cell mem-
brane
5. osmosis Low to High, Dittusion of water through a selectively permeable
membrane
6. Diffusion Movement of molecules from an area of higher concentration to an
area of lower concentration.
7. tonicity the ability of a surrounding solution to cause a cell to gain or lose water
8. isotonic solution when the concentration of two solutions is the same (moving in and
out equally)
9. hypertonic A solution in which the concentration of solutes is greater outside then
solu- tion
inside the cell that resides in the solution
10. hypotonic
Solute concentration is less than the inside the cell; cell gains water
solu- tion
11. oncotic pressure pulls fluid into the capillaries and/or prevents fluid from leaving.
12. hydrostatic increases filtration by pushing fluid and solute OUT of the capillaries
pres- sure
13. crenation This happens when a cell shrinks and shrivels; can result in cell death if
severe.
14. hemolysis destruction/split of red blood cells

17. Co-transport TWO substances are transported together by one protein no ATPase
activity
18. Countertrans One substance is being transported into the cell membrane and the

other is getting transported in the opposite direction.
