Aerobic Cyanobacteria Carry Out the Reactions of Nitrogen Fixation In

Question

Aerobic cyanobacteria carry out the reactions of nitrogen fixation in
A) akinetes.
B) endospores.
C) heterocysts.
D) chloroplasts.
E) lamellae.

Accepted Answer

Nitrogen fixation in aerobic cyanobacteria occurs in specialized cells called heterocysts. Heterocysts are specialized cells that have a thick cell wall, lack photosynthetic machinery, and have adapted to create an anaerobic environment that is essential for nitrogen fixation.
