Q: What is the role of Rhizobium bacteria in legume plants?
Solution:
Rhizobium bacteria form nodules on legume roots and fix atmospheric nitrogen, benefiting the plant.
Steps: 9
Show Steps
Step 1: Understand that Rhizobium bacteria are tiny living organisms.
Step 2: Know that these bacteria live in the soil.
Step 3: Recognize that legume plants (like beans and peas) have special roots.
Step 4: Learn that Rhizobium bacteria attach to the roots of legume plants.
Step 5: Understand that when Rhizobium bacteria attach, they form small lumps called nodules.
Step 6: Know that these nodules help the bacteria to take nitrogen from the air.
Step 7: Learn that nitrogen is an important nutrient for plants to grow.
Step 8: Understand that the bacteria convert the nitrogen into a form that the legume plants can use.
Step 9: Realize that this process helps the legume plants to grow healthier and stronger.
