Question

Location of pyrenoids in green algae
(A) Cytoplasm
(B) Plasma membrane
(C) Nucleus
(D) Chloroplast​

Answer 1

Answer:

Pyrenoids are sub-cellular micro-compartments found in chloroplasts of many algae,and in a single group of land plants, the hornworts.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). Pyrenoids therefore seem to have a role analogous to that of carboxysomes in cyanobacteria.

(D) is correct
