transport in plants - water from roots to leaves

Question 1

1

Answer 1

water molecules diffuse from the soil water into the root hair cells through osmosis

Question 2

2

Answer 2

water molecules diffuse from root hair cells to next cell through osmosis

Question 3

3

Answer 3

water molecules diffuse from cells in roots to the xylem through osmosis

Question 4

4

Answer 4

xylem transports water and mineral salts from roots to leaves

Question 5

5

Answer 5

water molecules diffuse out from the xylem vessel to the mesophyll cells through osmosis

Question 6

6

Answer 6

water continuously moves out mesophyll cells via osmosis to form a thin film of moisture around the surface of the mesophyll cells

Question 7

7

Answer 7

water (from thin film on mesophyll) evaporates to form water vapour in the intercellular air spaces

Question 8

8

Answer 8

Higher conc of WV in intercellular air spaces than surrounding air, water vapour moves out through the stomata during transpiration by diffusion
