Question 0

What kind of solution would cause water to flow OUT of a cell

Answer 0

Hypertonic

Question 1

What kind of solution would cause water to flow INTO a cell

Answer 1

Hypotonic

Question 2

Equilibrium is reached in which type of solution

Answer 2

Isotonic

Question 3

The diffusion of water through a selectively permeable membrane

Answer 3

Osmosis

Question 4

What process requires energy to pump molecules into/out of cells as needed

Answer 4

Active transport

Question 5

In diffusion molecules move from ______ to ______ concentration

Answer 5

High - low

Question 6

What does the cell membrane do

Answer 6

Controls what goes in/out of cell

Question 7

What is a cell membrane made of

Answer 7

Lipid bilayers

Question 8

What type of membrane proteins allow molecules to pass through

Answer 8

Protein channels

Question 9

What part of the cell membrane identifies the cell (and plays an important role in the immune system)

Answer 9

Carbohydrate chains

Question 10

Why shouldn’t you lick chapped lips

Answer 10

Enzymes in your saliva are used to break down your food

• -> break down your lips
• -> dry and cracked

Question 11

What kind of solution is saliva

Answer 11

Hypotonic

Question 12

If you placed a cell in a sokution, and it grew, what kind of solution is it

Answer 12

Hypotonic

Question 13

The shriveling of a cell is

Answer 13

Plasmolysis

Question 14

When you water a plant and water flows into a cell there is a build up of

Answer 14

Pressure

Question 15

Why shouldn’t we drink salt water

Answer 15

Salt dehydrates u

–> saltwater dehydrates u

Question 16

How can concentrations of salt INSIDE of cells be lowered if salt cannot pass through the membrane

Answer 16

Water will move using osmosis because water is allowed inside the cell allowing it to balance out salt/water creating an isotonic solution

Question 17

What affect does hypotonic solution have on a cell? Why?

Answer 17

Plant- causes cell membrane to push against cell wall = pressure build up and allows plant to stand upright

Animal- causes cell membrane to enlarge (w/o cell wall) it will burst

Question 18

In active transport, molecules move from areas of ____ concentration to ____ concentration

Answer 18

Low higj

Question 19

In osmosis moves from areas of ____ to _____ concentration

Answer 19

Low high

Question 20

Energy is used to move molecules in which cell transport processes

Answer 20

Wat LOL
