ANATOMY

Detailed explanation-1: -The xylem transports water and minerals from the roots up the plant stem and into the leaves.

Detailed explanation-2: -The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements. For example, the highest leaves will send sugars upward to the growing shoot tip, whereas lower leaves will direct sugars downward to the roots.

Detailed explanation-3: -The phloem is specialised to transport food products to parts of the plant where they are needed. Phloem vessels are made up of columns of living cells. The end walls of phloem cells contain small holes to allow food products to move up and down the phloem vessels.

Detailed explanation-4: -Phloem, also called bast, is a vascular tissue that runs through all the organs of plants. It transports sugars formed in the leaves during photosynthesis.

Detailed explanation-5: -4) Why is it important to the plant that phloem moves both up and down? A system for transporting materials in a plant or animal. Xylem moves water and nutrients up the plant from the roots to the leaves. Phloem moves sugar both up and down to deliver sugar to the plant.
