Answer 1

Ello user !!!!!!!!

Here is your answer,

============================================

Heterocysts are specialized nitrogen-fixing cells formed during nitrogen starvation by some filamentous cyanobacteria, such as Nostoc punctiforme, Cylindrospermum stagnale, and Anabaena sphaerica.

Nitrogenase is inactivated by oxygen, so the heterocyst must create a microanaerobic environment.

HOPE THIS HELPS YOUU :)
