1
. Pinocytosis Cell drinking Cell eating
release of substances outside a cell by the fusion of a vesicle
2 Phagocytosi with the membrane.
.
s
Exocytosis
34. 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
15. active transport the movement of ions or molecules across a cell membrane into a
1/

,region of higher concentration, assisted by enzymes and requiring
energy.
