Water Transport in Multicellular Plants

Question 1

Give four different adaptations of the root hair cell which makes it good for the transport of water

Answer 1

1. Microscopic size= can penetrate easily through soil particles
2. Microscopic size= large surface area: volume ratio which means that thousands of hair can be on each root
3. Thin surface layer (cell wall and plasma Membrane) means that diffusion and osmosis take place quickly
4. Concentration of soultes in cytoplasm Maintains a water potential gradient between soil water and cell

Mah, Mah, Mah,Mah…come on! (like the rihanna song, “I may bad but i’m perfectly good at it!”
