Question

Roots of this plant contain nitrogen fixing bacteria (a) mango (b) wheat (c) pea (d) maize

Answer 1

Root nodules occur on the roots of plants (primarily Fabaceae) that associate with symbiotic nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. ... The Fabaceae include legume crops such as beans and peas.

Answer 2

The correct option is c.

• In pea, beans etc some nitrogen-fixing bacteria are present.
• These bacterias contain many nitrogenase enzymes.
• Due to the presence of these nitrogenase enzymes conversion of nitrogen gas to ammonia take place at room temperature and normal pressure.
• The nitrogenase enzyme catalyses the reaction
• Thus we can say the roots of pea plants contain nitrogen-fixing bacteria.
