Question

Which statement about nitrogen fixation is false?

a) Nitrogen fixation is the conversion of atmospheric nitrogen into ammonia.
b) Nitrogen-fixing bacteria play a crucial role in nitrogen fixation.
c) Legumes form symbiotic relationships with nitrogen-fixing bacteria.
d) Nitrogen fixation occurs exclusively in eukaryotic cells.

Answer 1

Nitrogen fixation occurs in prokaryotic cells, not exclusively in eukaryotic cells.

Step-by-step explanation:

The statement d) Nitrogen fixation occurs exclusively in eukaryotic cells is false. Nitrogen fixation is the conversion of atmospheric nitrogen into ammonia. It is mainly carried out by prokaryotes, such as bacteria, that possess the enzyme nitrogenase. These bacteria play a crucial role in nitrogen fixation, including the symbiotic relationships formed with legumes. So, option d) is incorrect as nitrogen fixation can occur in prokaryotic cells as well.
