Chapter 7 Section 4

Question 0

Dynamic Equilibrium

Answer 0

Condition of continuous,random movement of particles but no overall change in concentration of materials

Question 1

Diffusion

Answer 1

Movement of particles From an area of high concentration to an area of lower concentration

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 cytoplasm the cell is in isotonic solution

Question 5

Hypotonic solution

Answer 5

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

Question 6

Hypertonic solution

Answer 6

The concentration of the solute outside of the cell is higher than inside

Question 7

Active transport

Answer 7

Energy requiring process by which substances move across the plasma membrane against a concentration gradient

Question 8

Endocytosis

Answer 8

Energy requiring process by which large substances from the outside environment can enter a cell

Question 9

Exocytosis

Answer 9

Energy requiring process by which a cell expels waste and secretes substances at the plasma membrane
