Question

Explain the mechanism of water transport in plant body.​

Answer 1

Answer:

Explanation:

The roots are in the soil, which is the major source of nutrients in plants. Water and other nutrients enter the plant through the roots.  The leaves are the food production centres. Using the sunlight and Carbon dioxide they synthesize food through photosynthesis in the chloroplasts.

Now, food from the leaves has to reach the other parts and the water, along with other nutrients has to reach leaves and other parts. All of this takes place through the vascular tissues of the plants.

the specialized cells and tissues in plants, which are the xylem and phloem. together, they constitute the vascular structure in plants.

The xylem tissue transports water and minerals from the roots to the leaves whereas the phloem tissue transports food from the leaves to the other parts of the plant. Xylem tissue has tracheids and vessel elements. Phloem tissue has companion cells and sieve tubes.

The phloem, on the other hand, is responsible for the translocation of the nutrients like carbohydrates and amino acids from the leaves to other areas of the plants. It moves up and down the stem.  Food movement in the phloem occurs due to the pressure flow mechanism.
