The molecular formula of chlorophyll b is:
Correct answer: A. C55H70O6N4Mg
- A. C55H70O6N4Mg
- B. C70H55O11N5Mg4
- C. C14H55O6N5Mg3
- D. C55H76O5N6Mg2
Explanation
The correct molecular formula of chlorophyll b is C55H70O6N4Mg. This formula indicates the presence of 55 carbon atoms, 70 hydrogen atoms, 6 oxygen atoms, 4 nitrogen atoms, and 1 magnesium atom. Option A is correct because it aligns with this molecular formula. Options B, C, and D have incorrect combinations of elements and quantities, making them incorrect choices for the molecular formula of chlorophyll b.

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.
