Question

what are pyrenoids?​

Answer 1

Answer:

Pyrenoids are sub-cellular micro-compartments found in chloroplasts of many algae,[1] and in a single group of land plants, the hornworts.[2] Pyrenoids are associated with the operation of a carbon-concentrating mechanism (CCM). Their main function is to act as centres of carbon dioxide (CO2) fixation, by generating and maintaining a CO2 rich environment around the photosynthetic enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO).
