Respuesta :
The question is incomplete as it does not have the options which are:
1. Transport soil solution to the vascular cylinder by bulk flow
2. Prevent the leakage of accumulated minerals back into the soil
3. Absorb the soil solution into the apoplast and symplast
4. Increase surface area of contact between the root epidermis and the soil solution
5. Block the flow of soil solution through the apoplast
Answer:
Option-3 and 4
Explanation:
The plants get their nutrients to survive from the atmosphere and the soil so to absorb nutrients and water present in the soil, plants evolved to form the roots. The higher plants evolved roots with root hairs (lateral extension of the root) which helped the plant in absorbing more nutrients.
The root hairs increase the surface area of the root to directly absorb the nutrients from the soil solution. The nutrients and water from the soil are absorbed by the root in their apoplast (the free space around the plasma membrane) and symplast (in the protoplast).
Thus, Option-3 and 4 are the correct options.
Answer:
The roots of the plants are important for the transportation of water and nutrients from the soil directly in to the plants. The root consists of small feathery like appearance known as root hairs.
The root hairs the ability to obtains mineral from the soil solution by both the symplast and apoplast pathyway takes place in plants. The roots hairs are also helpful in to increase the absorption surface area by making direct contact with the soil and root epidermis.
