Which of the following is NOT a function or characteristic of mesosomes in a bacterial cell?

Options

  1. AThey help in secretion processes.
  2. BThey contain pigments and participate in photosynthesis.
  3. CThey help in cell wall formation.
  4. DThey increase the surface area of the plasma membrane.

Correct answer

B. They contain pigments and participate in photosynthesis.

Step-by-step solution

Mesosomes are formed by the extensions of the plasma membrane into the bacterial cell. According to NCERT, their functions include cell wall formation, DNA replication and distribution to daughter cells, respiration, secretion processes, and increasing the surface area of the plasma membrane and enzymatic content. Membranous extensions that contain pigments and participate in photosynthesis are called chromatophores, which are found in some prokaryotes like cyanobacteria, not mesosomes. Therefore, the statement abo
