Question

to observe the rhizobium bacteria in the root nodules of the plant what are the appratus required​

Answer 1

Answer:

Leguminous family

Explanation:

They contain symbiotic bacteria called rhizobia within the nodules, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants and this helps to fertilize the soil.

Answer 2

Answer:

Rhizobium fixes gaseous nitrogen from the air into compounds plants can use to help them grow. An enzyme complex called nitrogenase catalyses this reaction. Nitrogenase activity is sensitive to the presence of oxygen. Root nodules may appear pink because they contain leghaemoglobin.
