Xylem And Phloem Structure

To solve this question, we need to identify which plant tissue, when removed, prevents the transportation of food in trees.

1. Understanding Plant Transport Systems:
Plants have two main vascular tissues for transportation:

• Xylem: Transports water and minerals from roots to leaves.
• Phloem: Transports food substances (sugars and nutrients) produced by photosynthesis from leaves to other parts of the plant.

2. Identifying the Correct Tissue:
Since the question specifically refers to the transportation of food, the tissue involved is phloem. Removal of phloem prevents food transport.

3. Evaluating Given Options:

• (1) Phloem – Correct; its removal prevents food transport.
• (2) Xylem – Incorrect; xylem transports water, not food.
• (3) Xylem vessels – Incorrect; specifically transport water.
• (4) None of the above – Incorrect; phloem is clearly involved.

Final Answer:
The correct answer is (A) Phloem.
