Question

What is the role of the xylem tissue? What kind of flow can be observed in xylem?

• A. Transporting food from leaves to other parts of a plant;material flow is bidirectional
• B. Supplying oxygen to different cells of the human bodymaterial flow is allowed for gases only
• C. Supplying both food and water to all parts of the plant;material flow is not allowed in xylem
• D. Transporting water from root to other parts of a plant;material flow is unidirectional

Answer 1

The correct option is D Transporting water from root to other parts of a plant;material flow is unidirectional

Xylem tissue is a type of plant vascular tissue that is responsible for the movement of water and minerals from the roots to all the different parts of the plant. It supplies only water and minerals. Xylem has unidirectional flow. Phloem is another type of plant vascular tissue that transports food from the leaves to all the different parts of the plant. Phloem has bidirectional flow.
