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
the movement of ions or molecules across a cell membrane into a region
of higher concentration, assisted by enzymes and requiring energy.
passive(facilitated) transport
the movement of substances across a cell membrane without the use of
energy by the cell

Co-transport
TWO substances are transported together by one protein no ATPase
activity
Countertransport
One substance is being transported into the cell membrane and the other
is getting transported in the opposite direction.
What are some factors that affect diffusion?
• Temperature
• Solvent Density
• Distance traveled
Simple Diffusion
high to low concentration easy to flow through cell membrane; Oxygen
is an example
Channel Mediated
Only the right shape gets through example little kid shape puzzles
List the three categories of transport across the cell membrane.
• Active transport
• Carrier Mediated
• Channel mediated
the structure of the mitochondrion
