Question

Explain symbiotic relationship between the following:
a. A fungus and an alga in case of a lichen.
b. Rhizobium bacteria and leguminous plants​

Answer 1

Answer:

1. A lichen is an organism that results from a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. ... The photosynthesizer benefits from the water and nutrients absorbed by the fungus.

2. Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.
