Osmosis in plants

Question 1

Osmosis

Answer 1

Movement of water from a high concentration to low concentration through a partially permeable membrane

Question 2

Plasmolysis

Answer 2

When the cytoplasm moves away from the cell wall

Question 3

Hypertonic solution

Answer 3

External solution that has
HIGH SOUTE concentration
LOW WATER concentration
compared to the cell

Question 4

Hypertonic solution plant cells

Answer 4

loss of water means cell loses mass and shrivels and becomes flaccid
Plasmolyse if water loss continues

Question 5

Hypotonic

Answer 5

External solution that has
LOW SOUTE concentration
HIGH WATER concentration
compared to the cell

Question 6

Hypotonic solution plant cells

Answer 6

The cell gains water and mass and swells up. The vacuole fills with water water and along with the cytoplasm which bushes against the cells wall.

Question 7

Isotonic solution plant cells

Answer 7

cell looks normal as water moved into and out of cell in equal amounts

cell neither gains or loses mass and so stays the same shape

Question 8

Isotonic

Answer 8

SAME water and solute concentration as the cell

Question 9

Why is turgor important

Answer 9

If a plant loses too much water from its cells so that they become flaccid, this means the plant will wilt. The leaves droop and collapse.

Question 10

Is the droop good?

Answer 10

protective measure from the plant

drooping leaves will cut down water loss by reducing exposed surface area of leaves and closing stomata.
