Q. With reference to complex permanent tissues in plants, consider the following statements:
1.Both Xylem and Phloem are considered conducting tissues and together they constitute the vascular bundle.
2.Xylem is primarily responsible for the unidirectional transport of water and minerals from roots to leaves.
3.Phloem consists of dead cells that transport food products from the leaves to the rest of the plant.
Which of the statements given above are correct?
Answer: A
Notes:
Explanation:
- Statements 1 and 2 are correct.
- Statement 3 is incorrect: Most cells in the Phloem (Sieve tubes, Companion cells) are living cells. Only Phloem fibers are dead. In Xylem, most cells (tracheids, vessels) are dead.
