In bacteria, the infoldings of the plasma membrane that form mesosomes function in
APhotosynthesis and accessory pigment production for the cell
BCell wall formation, DNA replication, and bacterial respiration
CStorage of starch, reserve food and other inclusion bodies
DSensing external chemical gradients and movement responses
Answer & Solution
Correct answer: B. Cell wall formation, DNA replication, and bacterial respiration
Mesosomes are membrane infoldings unique to prokaryotes. NCERT lists their functions as cell wall formation, DNA replication and distribution to daughter cells, and respiration. They are NOT photosynthetic per se.
