Dynamic equilibrium

Answer 1

There is continuous movement but no overall change

Question 2

Facilitated diffusion

Answer 2

Uses transport proteins to move other ions and small molecules across the plasma membrane

Question 3

Osmosis

Answer 3

The diffusion of water across a selectively permeable membrane

Question 4

Isotonic solution

Answer 4

When a cell is in a solution that has the same concentration of water and solutes as it is

Question 5

Hypotonic solution

Answer 5

When a cell is placed in a solution that has lower concentration of a solute

Question 6

Hypertonic solution

Answer 6

Concentration of solute outside of the cell is higher than inside

Question 7

Active transport

Answer 7

The movement of substances across the plasma membrane against a concentration gradient requires energy

Question 8

Diffusion

Answer 8

The net movement of particles from an area where there are many barnacles of the substance to an area where there are fewer particles of the same substance

Question 9

Endocytosis

Answer 9

Moves the large particles into the cell membrane surrounds it and then pinches away from the rest of the membrane and enters the cell

Question 10

Exocytosis

Answer 10

Opposite of endocytosis;excretes substances from the cell
