Nodulated root is character of pea family or leguminosae family becz. Nodules are found for nitrogen fixatation

Nodulated roots in Leguminosae

Leguminosae is a family of flowering plants that includes trees, shrubs, and herbs. One of the distinguishing features of this family is the presence of nodulated roots. Nodules are structures that form on the roots of leguminous plants, such as beans, peas, and clover, in response to infection by nitrogen-fixing bacteria known as rhizobia.

Anatomy of nodulated roots

The nodules are composed of plant cells and bacteria. They are formed when the rhizobia infect the root hairs of the plant. The bacteria multiply and induce the plant to form a nodule, which provides a suitable environment for them to fix nitrogen. The nodules have a pinkish-red color due to the presence of a pigment called leghemoglobin, which helps to transport oxygen to the bacteria.

Function of nodulated roots

The main function of nodulated roots is nitrogen fixation. Nitrogen is an essential nutrient for plant growth, but it is often limiting in the soil. Leguminous plants have evolved a symbiotic relationship with rhizobia that allows them to convert atmospheric nitrogen into a form that can be used by the plant. The plant provides the bacteria with a source of energy in the form of carbohydrates, while the bacteria provide the plant with fixed nitrogen.

Importance of nodulated roots

Nodulated roots are important for agriculture because they allow leguminous plants to grow in nitrogen-poor soils. They also reduce the need for synthetic fertilizers, which are expensive and can have negative environmental impacts. In addition, leguminous plants are an important source of protein for both humans and livestock.

Conclusion

In conclusion, nodulated roots occur in the Leguminosae family of plants. Nodules are specialized structures that form on the roots of leguminous plants in response to infection by nitrogen-fixing bacteria. They play an important role in nitrogen fixation, which is essential for plant growth and is often limiting in the soil. Leguminous plants are an important source of protein and can help to reduce the need for synthetic fertilizers.
