What is the role of Rhizobium in legume plants?
Correct Answer: Rhizobium bacteria help in nitrogen fixation in legume plants.
- Step 1: Understand that Rhizobium is a type of bacteria.
- Step 2: Know that legume plants include beans, peas, and lentils.
- Step 3: Recognize that Rhizobium bacteria live in the soil.
- Step 4: Learn that Rhizobium bacteria attach to the roots of legume plants.
- Step 5: Understand that when Rhizobium attaches, it forms small growths called nodules on the roots.
- Step 6: Know that these nodules help the bacteria to convert nitrogen from the air into a form that plants can use.
- Step 7: Realize that this process is called nitrogen fixation.
- Step 8: Understand that the fixed nitrogen helps the legume plants grow better and healthier.
