why do Root's epiblema and root hair absorb ions by spending energy
Answers
Explanation:
root's epiblema and root hair absorb ions by spending energy because the concentration of ions in the soil is less than that of in the roots. So it will require energy to move the ions from their low concentration to high concentration.
Answer:
plz mark me as brilliant and follow me.
Explanation:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
They cannot be absorbed by diffusion , because the minerals are in very low concentration. Instead, active transport is used. The root hair cells have carrier proteins in their cell membranes. ... Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.
