In chlorophyll 'a', the group attached to prophyrine ring is
Correct answer: B. methyl group
- A. hydroxyl group
- B. methyl group
- C. carboxyl group
- D. aldehyde group
Explanation
Chlorophyll 'a' is an essential pigment in photosynthesis, and its structure includes a porphyrin ring. Attached to this porphyrin ring is a methyl group (CH3). This is a distinguishing feature of chlorophyll 'a' as opposed to chlorophyll 'b', which has a formyl group instead. The hydroxyl, carboxyl, and aldehyde groups are not part of chlorophyll 'a's core structure.
