Cellular Transport

Question 0

Active transport is ?

Answer 0

The movement of substances from areas of low concentration to areas of high concentration and requires energy in the form of ATP and a protein “pump”

Question 1

Passive transport is ?

Answer 1

The movement of substances from areas of high concentration to areas of low concentration across a selectively permeable membrane without the use of energy.

Question 2

Diffusion

Answer 2

The movement of particles from areas high concentration to areas of low concentration.

Question 3

Osmosis

Answer 3

The movement of water from areas of high concentration to areas of low concentration across a selectively permeable membrane.

Question 4

Facilitated Diffusion

Answer 4

The passive transport of substances from areas of high concentration to areas of low concentration through a transport protein embedded in the cell membrane, usually for large molecules or charged molecules.

Question 5

Hypotonic solution

Answer 5

A solution that has less solutes (more water) than is present inside a cell.

Question 6

Hypertonic solution

Answer 6

A solution that has more solutes (less water) than is present inside a cell.

Question 7

Isotonic solution

Answer 7

A solution that has solute and water concentrations in dynamic equilibrium with the cell.

Question 8

A cell placed in a hypotonic solution will ?

Answer 8

Swell due to osmosis.

Question 9

A cell placed in a hypertonic solution will ?

Answer 9

Shrivel due to osmosis.

Question 10

A cell that is 30% water is placed in a solution that is 35% water, where will the water go?

Answer 10

Inside the cell, causing it to swell
