Answer 23

yes

Question 24

does Exocytosis use vesicles

Answer 24

yes

Question 25

Answer 25

active

Question 26

Endocytosis moves from...

Answer 26

high to low and low to high

Question 27

does Endocytosis use energy

Answer 27

yes

Question 28

does Endocytosis use proteins

Answer 28

no

Question 29

does Endocytosis use vesicles

Answer 29

yes

Question 30

is Endocytosis passive or active

Answer 30

active

Question 31

Hypertonic

Answer 31

- Higher concentration of solute outside - Water moves out of the cell - animal: Cells could shrivel - plant: Cells shrivel - cell membrane peels away from cell wall (plasmolysis)

Question 32

Isotonic

Answer 32

- Equal concentration of solute in/out - Water moves equally into/out of cell net 0 movement - plant & animal: Cells are in equilibrium

Question 33

Hypotonic

Answer 33

- Lower concentration of solute outside - Water moves into the cell - animal: Cells could burst (lyse) - plant: Cells will not burst, vacuole will take on excess water (turgor pressure)
