Describe adaptation in root hair for absorption of water
Answers
Answer:
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.
Answer:
Root hairs, or absorbent hairs, are tubular outgrowths of a trichoblast, a hair-forming cell on the epidermis of a plant root. These structures are lateral extensions of a single cell and are only rarely branched. They are found in the region of maturation, also called the zone of differentiation of the root. Just prior to and during root hair cell development, there is elevated phosphorylase activity.Plants absorb water through the roots from the soil by bulk flow citation needed. Root hair cells are adapted to this process by increasing root surface area for the purpose of taking in more water. The large vacuole inside root hair cells makes this intake much more efficiently
