Question

Assertion :Lichens are called dual plants. Reason: Since lichens possess alternation in their generation, they possess both sporophytic and gametophyte generation. Therefore, they are called dual plants.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is false but Reason is true
• D. Assertion is true but Reason is false

Answer 1

The correct option is D Assertion is true but Reason is false

It is true that lichens are called dual plants. This is because, in lichens, two organisms live in symbiotic association with each other. They are the algae and fungi. Algae are photosynthetic organisms. They prepare their own food and also provide nutrition to fungi. On the other hand, fungi provide protection and habitat to algae. So, both of them benefit mutually and they are said to be in symbiotic association with each other.

So, option D is the correct answer.
