Question

Explain symbiotic relationship in a) Lichen b) Leguminous plants

Answer 1

Answer:

a) Lichen is the symbiotic relationship between algae and fungi. Fungi provide the plant with water and minerals for photosynthesis. They also protect the plant from extreme heat and prevent them from being invaded by harmful bacteria. In turn, algae provide synthesized food to the fungi.

b) Leguminous plants such as pea contain rhizobium in their roots. Plants require nitrogen for their survival but they cannot what are take the atmospheric nitrogen directly from air. Rhizobium present in the roots convert atmospheric nitrogen into compounds of nitrogen (nitrates and nitrites) and release them in the soil. Plants absorb the nitrates and nitrites from the soil. In turn, they provide synthesized food to the rhizobium.
