Question

Heterocyst helps in :
(As Nitrogen Fixation
(B) Photosynthesis
(C) Protein synthesis
(D) Nucleic acid synthesis​

Answer 1

Answer:

option A is the answer

Explanation:

Nitrogen Fixation

Answer 2

Answer:

ans: (A) Nitrogen fixation

Explanation:

They fix nitrogen from dinitrogen (N2) in the air using the enzyme nitrogenase, in order to provide the cells in the filament with nitrogen for biosynthesis. Nitrogenase is inactivated by oxygen, so the heterocyst must create a microanaerobic environment.
