Osmotic Pressure

Question 1

Plant cells

Answer 1

Plant cells are typically bulging with water. We called this turgid. This keeps the plant up right

When a plant cell dies from dehydration it is called plasmolysis

Question 2

Animal cell

Answer 2

When an animal cells fills up with water and swells passed its capacity it bursts. We say it has lysed

When an animal cell loses water it shrivels

Question 3

Concentrations and osmotic pressure

Answer 3

Hypertonic-higher concentration of solute. (High solute means lower water concentration)

Hypotonic-lower concentration of solutes

Isotonic-Equal concentration of solute

Question 4

How does this affect your cells

Answer 4

Isotonic solution-Solutions that have even concentrations

When the concentration of water is equal inside and outside the cell there is even movement in and out of the cell

Question 5

Swelling

Answer 5

Hypotonic solution-
Lower concentration of solute in the water outside the cell

If there is a lower concentration of solute outside in the water concentration outside is higher in the water will move inside causing the cell to swell

Question 6

Shrinking

Answer 6

Hypertonic solution-
Greater concentration of solute in the water outside the cell

If there is a greater concentration of solute outside in the water concentration outside is low in the water will move outside

Question 7

Turgor pressure

Answer 7

This is the measure of water pressure in a cell. If too much water flows out of plant cells then the plant wilts
