Question

Monerans showing oxygenic photosynthesis

• A. Are photolithotrophs
• B. Have non peptidoglycan nature of cell wall
• C. Have p hotoorganotrophic mode of nutrition
• D. Are Gram positive bacteria

Answer 1

Answer: (A), (B)

The correct options are
A Are photolithotrophs
B Have non peptidoglycan nature of cell wall

All oxygenic photosynthetic monerans are photolithotrophs since they require light for the process of photosynthesis. Cyanobacteria is an excellent example for oxygenic photosynthesis and their cellwall is made of peptidoglycan layer.

So, the correct options are 'are photolithotrophs & have non peptidoglycan nature of cell wall'.
