Question

Explain the mechanism of transport of water, food and other substances in a plant.​

Answer 1

Plants have two transport systems to move food, water and minerals through their roots, stems and leaves. These systems use continuous tubes called xylem and phloem, and together they are known as vascular bundles.Plants have two different types of 'transport' tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant.

Answer 2

The plants transport food and water through the vascular tubes.

• Plants have vascular bundles, which run from the roots to the leaves for the conduction of water and food in the plants.
• The vascular tube which transports water from the roots to the leaves is known as the xylem.
• On the other hand, the vascular tube which transports food from the leaves to all other parts of the plant is named as phloem.
• The transpiration pull is the reason for the transport of water through the xylem tube.
