SB1i - Transporting Substances: Osmosis

Question 1

What is the definition of osmosis?

Answer 1

The diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane

Question 2

What concentration do dilute solutions contain?

Answer 2

A high water concentration

Question 3

What do partially permeable membranes do?

Answer 3

Allow some molecules to pass through

Question 4

What is osmosis simply?

Answer 4

The diffusion of water

Question 5

What kind of solution of the cell’s cytoplasm?

Answer 5

Relatively concentrated

Question 6

What happens when putting an animal cell in water?

Answer 6

Osmosis happens and water moves from the outside of the cell where concentration is lower and into the cell where the concentration is higher and there is less water causing the cell to expand

Question 7

What happens when you put an animal cell into a more concentrated solution

Answer 7

Water will move out if the cell where concentration is higher and the ceiling will shrink

Question 8

after putting a plant cell in water, what prevents it from bursting?

Answer 8

It’s cell wall

Question 9

What is it called when a cell becomes swollen?

Answer 9

Turgid

Question 10

What does a flaccid cell mean?

Answer 10
