Question

Lichens show the symbiotic association between

• A. Algae and fungi
• B. Fungi and bacteria
• C. Bacteria and virus
• D. Fungi and roots of higher plants

Answer 1

The correct option is A Algae and fungi

A lichen is a stable symbiotic association between a fungus and algae and/or cyanobacteria. The lichen symbiosis is thought to be a mutualism, as both the fungi and the photosynthetic partners, called as photobionts, benefit. The algal component photosynthesize and provide food for the fungus while the fungal component provide protection from the environment by its filament.

Thus, the correct answer is option A.
