GCU BIO-201 EXAM 1 QUESTIONS
AND 100% CORRECT ANSWERS| 2026
UPDATED
Pinocytosis
Cell drinking
Phagocytosis
Cell eating
Exocytosis
release of substances outside a cell by the fusion of a vesicle with the membrane.
Endocytosis
process by which a cell takes material into the cell by infolding of the cell
membrane
,osmosis
Low to High, Diffusion of water through a selectively permeable membrane
Diffusion
Movement of molecules from an area of higher concentration to an area of lower
concentration.
tonicity
the ability of a surrounding solution to cause a cell to gain or lose water
isotonic solution
when the concentration of two solutions is the same (moving in and out equally)
hypertonic solution
A solution in which the concentration of solutes is greater outside then inside the
cell that resides in the solution
, hypotonic solution
Solute concentration is less than the inside the cell; cell gains water
oncotic pressure
pulls fluid into the capillaries and/or prevents fluid from leaving.
hydrostatic pressure
increases filtration by pushing fluid and solute OUT of the capillaries
crenation
This happens when a cell shrinks and shrivels; can result in cell death if severe.
hemolysis
destruction/split of red blood cells
active transport
