ATI Science- Osmosis/Diffusion

Question 1

a substance that can be dissolved in a “solvent”

Answer 1

solute

Question 2

substance in which a “solute” is dissolved

Answer 2

solvent (solvent is doing the bending)

Question 3

-tonic mean

Answer 3

strength

Question 4

has higher solute concentration in the solution than the cell inside of the solution

Answer 4

hypertonic solution

Question 5

has lower solute concentration in the solution than the cell inside of the solution

Answer 5

hypotonic

Question 6

has same amount of solute inside the solution, as the cell inside of the solution

Answer 6

isotonic

Question 7

The cell ______ in a hypertonic solutions

Answer 7

shrinks

Question 8

The cell _______ in a hypotonic solution

Answer 8

swells

Question 9

Movement of molecules/ions against a concentration gradient is an example of ______ transport

Answer 9

active transport

Question 10

Property of water

Answer 10

Water dissolves polar ionic compound

Question 11

In a hypertonic solution, water flows through aquaporins embedded in the plasma membrane of the cell. This type of transport is best known as which of the following

Answer 11

Osmosis

Question 12

Which of the following is an example of active transport?

Answer 12

Movement of sodium and potassium against their concentration gradient

Question 13

when molecules passively move from high to low concentration

Answer 13

diffusion

Question 14

passive movement of water through a semi permeable membrane, from a low solute concentration to a high solute concentration

Answer 14

osmosis

Question 15

passive transport vs active transport

Answer 15

does not require energy vs requires energy
