Question
Assertion :Most minerals must enter the root by active absorption into the cytoplasm of epidermal cells. Reason: This transportation needs energy in the form of ATP. Some ions also move into the epidermal cells passively.

Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- There are two ways of absorption of mineral nutrients from the soil in the plants. They are active and passive absorption.
- Most of the minerals enter the root by active transport into the cytoplasm of the epidermal cells.
- Active absorption of mineral ions is a complex process as it takes place against the gradient. So, it needs energy in the form of adenosine triphosphate (ATP).
- Passive absorption of minerals occurs along with the absorption of water through the root hairs, towards the gradient.
So, the correct answer is option A.
