Question

The xylem in plants are responsible for

• A. Transport of water
• B. Transport of food
• C. Transport of amino acid
• D. Transport of oxygen

Answer 1

The correct option is A

Transport of water

The correct option is A.

Explanation of the correct option:

• Xylem is a vascular tissue. It is used for the conduction of water.
• Xylem is also termed as conducting tissue.
• Xylem helps get water from the roots to the plant body, such as leaves and stems.
• Xylem is composed of tracheids, fibers, vessels, and parenchyma.

Explanations of the incorrect options:

Option B:

• Phloem transports food to all the parts of the plant.
• The direction of flow of phloem is downward.

Option C:

• Amino acids are transported to the leaves of the plant.
• Amino acids are transported to the leaves through the xylem transpiration stream.
• The phloem then transports the amino acids to the sink tissues.

Option D:

• Transport of oxygen is carried out by the vascular tissues.
• However, the gaseous exchange in the plants is mostly through the stomata and lenticels.

Therefore, the xylem is responsible for water transport in the plants.
