Question

Food is translocated in plants by

• A. Xylem tissue cells
• B. Phloem tissue cells
• C. Both these cells
• D. None of these

Answer 1

The correct option is B

Phloem tissue cells

The correct option is B.

Explanation of correct option:

The process of transporting food to the different parts of the plant from the leaves where it synthesizes by photosynthesis is called the translocation of food. It is an essential process as food is required for all parts of the plant for cellular functions.

1. Phloem tissue cells are the tissues that help transport the food from the leaves to the various parts of the plant.
2. Sieve tubes are the part of the Phloem and the entry point for food molecules or sucrose and move to various organs throughout the plant body including roots.
3. Companion cells are also present adjacent to the sieve tubes or elements.

Explanation of incorrect option:

Option A:

Xylem tissue cells are accountable for the movement of the water from the roots to the various parts of the plant body including leaves. It transports water and only upwards to the leaves and stem.
