animal and plant cells comparison osmosis

Question 1

Which cell has a cell membrane

Answer 1

present composed of phospholipid bilayer

partially permeable

Question 2

Which has a cell wall animal or plant

Answer 2

plant made of cellulose

partially permeable

Question 3

In which cell can osmosis occur

Answer 3

both

Question 4

similarities when a cell is placed in a low potential solution

Answer 4

Water leaves cell through partially permeable membrane

volume of cell decreases

Question 5

Differences when a cell is placed in a low water potential solution

Answer 5

plant: protoplast shrinks / pulls away from cell wall

cell is plasmolysed

animal :

cell shrinks / shrivelled

Question 6

similarities Cell placed in a solution with high water potential

Answer 6

Water moves in the cell through partially permeable membrane

volume of cell increases

Question 7

Differences when cells are placed in solution with high water potential

Answer 7

plant: protoplast expands/ pushes against cell wall

cell wall withstands increasing pressure

Pressure increases till cell is turgid (rigid and firm

cell is fully inflated no water can get in

animal:

No cell wall to withstand pressure

cell membrane eventually stretched to far and will burst
