Phloem is the tissue in the plant system that transports the nutrition and the food materials to the plant parts. It is composed of many specialized cells like fibres, parenchyma cells, companion cells and sieve tubes.

Phloem's end walls have openings that let water and nutrients pass through them.

How does the structure of phloem help in transportation?

The tissue of the transporting system has small openings at their end sections that allow the passage of the food and water up and down the vessels of the plant.

The tiny holes present for the exchange of gases and water are called stomata while the root hair changes its shape to absorb water from the soil.

Therefore, option A is correct.
