Osmosis

Question 1

Osmosis

Answer 1

The movement of water from a dilute solution to a more concentrated solution through a selectively permeable membrane

Question 2

Why do plants need water?

Answer 2

1) Support (turgor)
2) Transpiration
3) Transport (of minerals)
4) As a raw material in Photosynthesis

Question 3

Turgor/Turgid

Answer 3

When a plant cell has gained enough water by osmosis causing its membrane to push against the cell wall, making it firm.

Question 4

Plasmolysis/Plasmolysed

Answer 4

When a plant cell has lost enough water by osmosis that the membrane pulls away from the cell wall.

Question 5

Transpiration

Answer 5

The evaporation of water from mesophyll cells, followed by diffusion through the leaf air spaces and stomata

Question 6

Factors that affect the Rate of Transportation

Answer 6

1) Temperature
2) Wind-Speed (use fan)
3) Humidity (plastic bag)
4) Light (place in cupboard)
5) Surface Area
