The Cell

Front 1

Property that allows nutrients to enter the cell but keeps out undesirable substances

Back 1

Selective permeability

Front 2

Passive processes

Back 2

diffusion and filtration

Front 3

Concentraion gradient

Back 3

difference in concentration

Front 4

The movement of molecules from a region of their higher concentration to their lower concentration

Back 4

Diffusion

Front 5

Unassisted diffusion of solutes (dissolved substance) through a different permeable membrane

Back 5

simple diffusion

Front 6

Passive transport process where small ions cross the membrane by moving through water-filled protein channels

Back 6

facilitated diffusion

Front 7

Osmosis

Back 7

Flow of water across a differentially permeable membrane

Front 8

Cells retain their normal size and shape (same solute/water concentration) no osmosis

Back 8

Isotonic solutions

Front 9

Cells lose water by osmosis and shrink (higher level of concetration of solutes than inside the cell)

Back 9

Hypertonic solutions

Front 10

Cells take on water by osmosis until they become bloated and burst (lower level of concentration solute than inside the cell)

Back 10

Hypotonic solutions

Front 11

Passive process by which water and solutes are forced through a membrane by fluid pressure

Back 11

Filtration

Front 12

Large particles are transported across the membrane by

Back 12

Vesicular transport

Front 13

Movement into the cell

Back 13

endocytosis

Front 14

Movement out of the cell

Back 14

exocytosis

Front 15

Cell eating~cellular extensions flow around the external particle and enclose it within the vacuole

Back 15

Phagocytosis

Front 16

Dissolved proteins gather on the external surface of the plasma membrane, and drop tiny bits of fliud into the vesicle

Back 16

Pinocytosis

Front 17

Plasma membrane proteins bind only with certain substances in regions of coated pits (protein-coated vesicles)

Back 17

Receptor-mediated endocytosis
