What Is Called Heterocyst?

Heterocysts are specialized nitrogen-fixing cells, produced by some filamentous cyanobacteria, which form during nitrogen starvation conditions. These specialized cells do not possess functioning photosynthetic apparatus because their primary function is the anaerobic fixation of atmospheric nitrogen [40].

What Is Heterocyst Answers?

Complete answer: Heterocyst is the specialized nitrogen-fixing cell found in cyanobacteria or blue-green algae. These are formed by blue-green algae during the condition of nitrogen deficiency. Some of the examples are Nostoc punctiforme, Cylindrospermum stagnale, and Anabaena sphaerica.

What Is Heterocyst Class 11 Ncert?

Heterocyst is a transparent thick-walled empty cell that is present in the filaments of blue-green algae. They are formed during cases of nitrogen starvation. They are the site of nitrogen fixation as they contain the enzyme nitrogenase required for nitrogen fixation. The main function of heterocyst is to fix nitrogen.

Is Anabaena A Heterocyst?

The Anabaena genus is a model organism of filamentous cyanobacteria whose vegetative cells can differentiate under nitrogen-limited conditions into a type of cell called heterocyst. These heterocysts lose the possibility to divide and are necessary for the colony because they can fix and share environmental nitrogen.
