In leguminous plants, there exists a symbiotic association between the plant and the bacterium. Choose the correct statement regarding this.
Options
- AThe bacteria derive reduced from plant
- BThe bacteria supply reduced to the plant and receive sugars from plant
- CThe nodule is produced by the plant independent of bacteria
- DThe plant growth is inhibited by the factors produced by bacteria
Correct answer
B. The bacteria supply reduced to the plant and receive sugars from plant
Step-by-step solution
Legumes form a unique symbiotic relationship with bacteria known as Rhizobium, which they allow to infect their roots. This leads to root nodule formation where bacteria are accommodated to convert nitrogen from the air into ammonia that the plant can use for growth. In turn, bacteria receive food from the plants in the form of sugars.
