Fungi helps the algae harves
Options
- AII and III
- BI and III
- CI, II and III
- DIII and IV
Correct answer
B. I and III
Step-by-step solution
Lichens are a symbiotic association of the algae (phycobiont) and fungi (mycobiont). The algal partner produces food and the fungal partner provides protection to the algae. The fungi also help in absorption of minerals and water. Lichens generally do not grow in polluted areas, hence they are good indicators of pollution.
