Question

What name is given to the bacteria found in the root nodules of pea plants? State their importance.

Answer 1

Solution

Rhizobium Bacteria are found in the root nodules of pea plants.
It helps the pea plant by trapping the nitrogen from the atmosphere and convert it into nitrate form (mineral salts) so that it can easily be absorbed from the soil by plants along with water.
Pea plant acts as a host for bacteria and provides shelter to live and in return, bacteria helps the plant to generate food.
The relationship in which the organisms help each other in some or the other way is called symbiosis and the organisms are called symbionts.
