Question

Assertion : Vascular or conductive tissue is a distinctive feature of complex plants. Reason : Vascular tissue has made survival of complex plants possible in a terrestrial environment.

Answer 1

Answer:

Answer: Vascular or conductive tissue is the tissue of higher plants, which enables them to survive in terrestrial environment. Both xylem and phloem are conducting tissues of higher plants. The distinctive feature of this tissue is, it is a complex tissue which conducts food and water.

Explanation:

Answer 2

Both Assertion and Reason are true and reason is correct explaination of assertion.

• Vascular tissues are distinctive features of the complex plants. These vascular tissues aren't present in lower plants like Thallophytes , Bryophytes. Hence, the given assertion, vascular or conductive tissue is a distinctive feature of complex plants is absolutely correct.
• It's only because of the presence of vascular bundles like xylem and phloem , complex plants survive for long. Xylem plays an important role in transportation of water and minerals while phloem is very important for food conduction .
• Moreover, xylem fibres and phloem fibres provide mechanical strength to the plant body.
• Hence, it would be correct to say that vascular tissue is an distinctive feature of complex plants which make their survival possible in terrestrial environment.
