Question

Bacteria do not have chloroplast but some bacteria are photoautotrophic in nature and perform photosynthesis. Which part of bacterial cell performs this?

• A. Small vesicles associated with plasma membrane
• B. Mitochondria
• C. Ribosomes
• D. None of the above

Answer 1

The correct option is A Small vesicles associated with plasma membrane

Bacterial cells do not have chloroplast but some photoautotrophic bacteria perform photosynthesis in the presence of chlorophyll incorporated in the cell membrane. Embedded in the cell membrane are reaction centres which absorb light energy. These reaction centres exists in the form of sacs or tubes or sheets depending on the surface area needed.

Mitichondria is absent and ribosomes are involved in protein synthesis.

Hence the correct option is A.
