Question

More than 90 percent of all nitrogen are fixed as ammonia, nitrites, and nitrates by soil microorganisms. Symbiotic bacteria associated with leguminous plants fix nitrogen by the formation of root nodules. In which of the following plant nitrogen fixation does not occurs?

Oats

PYQPulse · Answer

Explanation: Oats undergo C3 photosynthesis, which is a type of carbon fixation. In C3 photosynthesis, the primary carbon fixation process occurs in the mesophyll cells of the plant's leaves. The enzyme responsible for carbon fixation in C3 plants is ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). Hence option D is incorrect.
