• A. xylem
• B. phloem
• C. stomata
• D. root hair

Answer 1

The correct option is A

xylem

The correct option is A.

Explanation for the correct option:

1. The xylem is the vascular tissue of the plant that helps in the transportation of water and nutrients from the roots.
2. It is unidirectional.

The phloem helps in the transport of food.

Option C:

Stomata are small minute pores on the leaf surface that help in the transfer of gases.

Option D:

Root hair is minute hair-like extensions present on the root that help in increasing the surface area of the root and assist in absorbing more nutrients and water from the soil.

Final answer: In plants, water is transported through the xylem.
