Sagot :
Answer:
B
Explanation:-
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
I hope it helps.
Answer:
[tex]\huge\boxed{\sf Option \ B}[/tex]
Explanation:
When there is a high concentration of mineral salts in the root hair cells (high concentration of solute), this results in osmosis.
Osmosis is:
"The movement of water molecules (or solvent molecules) from a region of low solute potential to a region of high solute potential through a semi-permeable membrane."
Process of absorption of water through root hair cells:
So, since, the solute conc. is high in the root hair cells, the solvent (water) conc. is low, this means that more water will move into the root hair cells due to osmosis with the membrane of root hairs as semi-permeable membrane!
