Question

Explain symbiotic realtionship in : a). Lichen b). Legnminous plant with Rhizobium bacteria .​

Answer 1

Explanation:

@) Lichen is the symbiotic relationship between algae and fungi. ... 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.

Answer 2

• A) A lichen is a composite organism that arises from algae or cyanobacteria (or both) living among filaments of a fungus in a symbiotic relationship. The combined life form has properties that are very different from the properties of its component organisms. The fungus benefits from the symbiotic relation because algae or cyanobacteria produce food by photosynthesis. The algae or cyanobacteria benefit by being protected from the environment by the filaments of the fungus, which also gather moisture and nutrients from the environment, and (usually) provide an anchor to it.
• B) 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.
