Cell Transport Quiz

Question 0

• The diffusion of water through a selectively permeable membrane
• water diffuses across a membrane from an area of high concentration to an area of low concentration

Answer 0

Osmosis

Question 1

• The movement of small particles across a selectively permeable membrane until equilibrium is reached
• these particles move from an area of high concentration to an area of low concentration

Answer 1

Diffusion

Question 2

The movement of larger molecules like glucose through the cell membrane- larger molecules must be “helped”

Answer 2

Facilitated diffusion

Question 3

Contains a high concentration of solute relative to another solution when it is placed to this solution, the water diffuses out of the cell, causing it to shrivel

Answer 3

Hypertonic solutions

Question 4

Contains a low concentration of solute related to another solution. When a cell is placed in this solution, the water diffuses into the cell, causing the cell to swell and possibly explode

Answer 4

Hypotonic solutions

Question 5

Contains the same concentration of solute as another solution. When a cell Is placed in this solution, the water diffuses into and out of the cell at the same rate

Answer 5

Isotonic solutions

Question 6

The movement of molecules from low to high concentration

Answer 6

Active transport

Question 7

-Separates the components of the cell from its environment surrounding the cell
-“Gatekeeper” of the cell – regulates the flow of materials into and out of the cell – selectively permeable.
– Help cells maintain homeostasis

Answer 7

Cell membrane

Question 8

The process that does not require energy to move molecules from a high to low concentration

Answer 8

Passive transport

Question 9

– Diffusion
– Facilitated diffusion
– osmosis

Answer 9

Three types of transport

Question 10

–Particles moving from one place to another

– Moves down the concentration gradient from areas of high concentration to areas of low concentration

Answer 10

Net diffusion
