Detailed explanation-1: -Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.

Detailed explanation-2: -Phloem is a vascular tissue helps in the transportation of food. The end product of photosynthesis is glucose [C6H12O6] synthesized in leaves and transported to the various storage organs like flowers, fruits, seeds and tubers etc.

Detailed explanation-3: -From what you know about osmosis, explain why water follows the sugar as it moves through the Phloem. Water molecules always move to areas of high solute concentration via osmotic pressure.

Detailed explanation-4: -Photosynthesis occurs in the mesophyll cells of leaves. From the leaves, phloem tissue transports it to all other parts of the plant. Phloem tissue is made up of tubular interconnected cells.

Detailed explanation-5: -It is important to the plant that the phloem moves both up and down because the movement of food and nutrients created during photosynthesis throughout the plant is accomplished by the phloem.
