Unit 2 Diffusion

Question 1

If solution is isotonic,

Answer 1

-it’s osmolarity and water potential are the same
-water potential at equal concentration

Question 2

If a solution is hypertonic,

Answer 2

-It’s osmolarity is high, and it’s water potential is low
-high solute

Question 3

If a solution is hypotonic,

Answer 3

-It’s osmolarity is low, and it’s water potential is high
-low solute

Question 4

What is osmosis?

Answer 4

The movement of water through a semi permeable membrane

Question 5

In Osmosis, water travels…

Answer 5

water travels from an area of high concentration to an area of low concentration

Question 6

Water has a tendency to move towards areas

Answer 6

where there is a higher solute concentration

Question 7

Water Potential…

Answer 7

…can be used to measure the ability of water molecules to flow freely inside a given environment

Question 8

What are the two types of endocytosis?

Answer 8

phagocytosis(solid) and pinocytosis(liquid)

Question 9

Are Endocytosis and Exocytosis passive or active forms of transport?

Answer 9

Active, it requires energy to move large molecules across the cell membrane

Question 10

Water potential equation:

Answer 10

water potential = pressure potential + solute potential
