Effect Of Osmosis On Plant And Animal Cells

Question 1

What does turgid mean?

Answer 1

The state of a plant cell which contains the maximum amount of water it can hold. The cell contents are swollen and push against the cell wall. A tissue in which the cells are turgid will be firm and so turgidity contributes to the support of the plant.

Question 2

What does plasmolysed?

Answer 2

The condition of a plant cell which has lost water by osmosis to the extent that its vacuole and cytoplasm have shrunken away from the cell wall.

Question 3

What happens to a plant cell when the water concentration is the same on the inside and outside of the cell?

Answer 3

The cell has no change when placed in a solution of equal concentrations.

Question 4

What happens to a plant cell when the water concentration is higher outside the cell?

Answer 4

The water passes though the cell membrane by osmosis and the cell becomes turgid.

Question 5

What happens to a plant cell when the water concentration is higher inside the cell?

Answer 5

The water passes out the cell membrane by osmosis and the cell becomes plasmolysed.

Question 6

What happens to an animal cell when the water concentration is the same inside and outside of the cell?

Answer 6

There is no change when it is placed in solution if equal concentration.

Question 7

What happens to an animal cell when the concentration is higher outside the cell?

Answer 7

The water passes in through the cell membrane by osmosis and the cell swells causing the cell to burst.

Question 8

What happens to an animal cell when the water concentration is hight inside the cell?

Answer 8

The water passes through the cell membrane by osmosis causing the cell to shrink.
