Question

Lichens are mutualistic relationship between:

• A. Fungus and photosynthetic algae
• B. Fungus and cyanobacteria
• C. Fungus and roots of higher plants
• D. Both (A) and (B)

Answer 1

The correct option is D Both (A) and (B)

D. Both (A) and (B)

Solution: Lichens are mutualistic association between algae and fungi. Most of the time the algae is a cyanobacteria. In this association, the algal part produces food by photosynthesis and supplies that to the fungal part. On the other hand, the fungal part adsorbs water and minerals from soil and supplies those to the algal part. In this association, both the organisms are benefited and hence it is an example of mutualism.

So the correct answer is "Both (A) and (B)".
