Question

2. Sow the gram or bean seeds in soil. Water the soil regularly. After the plant grows to
certain height, pull out the plant from the soil. Observe its roots. You will find round
structures called root nodules on the roots. Draw a diagram of the root and show the
root nodules.​

Answer 1

Explanation:

The appearance of the galls on the roots can be confused with nitrogen-fixing nodules common in the legume family. However it is easy to distinguish between them, as the nitrogen nodules can be easily rubbed off while the nematode galls cannot be removed.
