Answer:
Roots take in water and nutrients by absorbing them through their surface cells .
Note :- Presence of roots hair increases the area available for absorption.
plants absorbs most of the minerals through the roots .
Most nutrients are absorbed through root hairs near the tip of the roots .
They absorbs mineral ions by active transport , against the concentration gradient .
Roots are also known as epidermal cells.

Epidermal cells help plants in absorbing water and nutrients from the soil through the process of osmosis.
Explanation:
- Roots in plants have epidermal cells in their outer layer and these cells conduct the process of osmosis through which the water and nutrients from the soil are absorbed.
- The mineral ions get absorbed through the process of active transportation and this occurs against the gradient of concentration.
- The cells in the root hair get adapted for taking up these minerals and water as they have a large surface area and this enhances the rate of absorption and osmosis.
