Answer:
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.
When transpiration in plants occurs, water gets evaporated from the leaves. This results in more water being pulled from the root. This phenomenon explains how water moves up in the plants, against gravity, without the use of any pump! The flow of water in the xylem tissues is unidirectional. It moves up the stem from the roots. It occupies the centre of the vascular bundle.
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. Here, the flow is bidirectional. It moves up and down the stem. Phloem occupies the edge of the vascular bundle, as seen in the following figure. Food movement in the phloem occurs due to the pressure flow mechanism. The differences in the osmotic pressure help in the movement of food from the area of high concentration to to areas of low concentration.
