Question

Rhizobium supplies nitrogen to leguminous plants by

Options

A)
changing some mineral salts to sulphate of ammonia
B)
incoporating urea into its body
C)
fixing atmospheric nitrogen
D)
decomposing plant remains
E)
increasing the PH value of the soil

The correct answer is C.

Explanation:

Rhizobium supplies nitrogen to leguminous plants by fixing atmospheric nitrogen. This means that Rhizobium bacteria have the ability to convert the nitrogen gas in the atmosphere into a form that plants can use. Nitrogen is an essential nutrient for plant growth, and leguminous plants, such as beans and peas, have a special relationship with Rhizobium bacteria.

When leguminous plants grow, they form nodules on their roots. These nodules contain the Rhizobium bacteria. The bacteria take in nitrogen gas from the air and convert it into a form called ammonia through a process called nitrogen fixation. The ammonia is then used by the plant to make proteins and other important molecules.

This symbiotic relationship between Rhizobium bacteria and leguminous plants is beneficial for both parties. The bacteria provide the plants with a source of nitrogen, which is necessary for their growth and development. In return, the plants provide the bacteria with carbohydrates and other nutrients.

It is important to note that Rhizobium bacteria are not the only organisms that can fix atmospheric nitrogen. There are other types of bacteria and some plants, such as certain types of algae, that can also perform nitrogen fixation. However, Rhizobium bacteria are specifically associated with leguminous plants and play a crucial role in their nitrogen supply.
