high to low and low to high

27
Q

does Endocytosis use energy

A

yes

28
Q

does Endocytosis use proteins

A

no

29
Q

does Endocytosis use vesicles

A

yes

30
Q

is Endocytosis passive or active

A

active

31
Q

Hypertonic

A
  • 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)
32
Q

Isotonic

A
  • Equal concentration of solute in/out
  • Water moves equally into/out of cell net 0 movement
  • plant & animal: Cells are in equilibrium
33
Q

Hypotonic

A
  • 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)
