Cell Transport key

Question 1

movement of substances across the cell membrane without any input of energy by the cell

Answer 1

PASSIVE TRANSPORT

Question 2

movement of molecules from high to low [ ] (concentration)
- driven by the concentration gradient
- spreads out evenly till dynamic equilibrium is reached

Answer 2

DIFFUSION

Question 3

A solution that has the same level of concentration

Answer 3

ISOTONIC

Question 4

Diffusion of water

Answer 4

OSMOSIS

Question 5

A solution that contains more water than solute

Answer 5

HYPOTONIC

Question 6

A solution that contains more solute than water

Answer 6

HYPERTONIC

Question 7

cell bursts due to water entering the cell

Answer 7

CYTOLYSIS

Question 8

cells shrink when turgor pressure is lost
- the reason plants wilt

Answer 8

PLASMOLYSIS

Question 9

move molecules across the cell membrane through carrier/transport proteins
- are specific for the type of molecule they help diffuse

Answer 9

FACILITATTED DIFFUSION

Question 10

substances can cross the cell membrane with an input of energy from the cell

Answer 10

ACTIVE TRANSPORT

Question 11

the process by which cells ingest “stuff”
- vesicle holds the “stuff”
- two types:

Answer 11

ENDOCYTOSIS

Question 12

solutes and fluids

Answer 12

PINOCYTOSIS

Question 13

large particles or whole cells

Answer 13

PHAGOCYTOSIS

Question 14

the process by which cells release “stuff”
- is essentially the reverse of endocytosis

Answer 14

EXOCYTOSIS
