Question

8. When plants absorb water and minerals from the soll, not all of the water absorbed is
utilived within the plant. What happens to the excess water, and how is this helpful to the
plant body?​

Answer 1

Answer:

.............

Explanation:

Water and mineral salts first enter through the cell wall and cell membrane of the root hair cell by osmosis. Root hair cells are outgrowths at the tips of plants' roots (Figure 5.27). They function solely to take up water and mineral salts.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.
