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.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
