Show Answer

Answer:

Correct Answer: C

Solution:

Nostoc is a genus of blue-green algae or cyanobacteria. They are prokaryotic and perform photosynthesis12.

Nostoc contains polyhedral bodies, also known as carboxysomes.

These are proteinaceous microcompartments present in many bacteria and some archaea. Carboxysomes are involved in carbon fixation, as they contain the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and carbonic anhydrase.

Therefore, the correct answer is C) Nostoc.
