The tail of chlorophyll molecule is embedded in:
Correct answer: B. Thylakoid membrane
- A. Membrane of mitochondria
- B. Thylakoid membrane
- C. Membrane of Smooth Endoplasmic Reticulum
- D. Membrane of Rough Endoplasmic Reticulum
Explanation
The thylakoid membrane of the chloroplasts has these light-harvesting clusters called photosystems which contain various pigments needed to absorb light. These pigments, including chlorophyll, have their tails embedded in the thylakoid membrane as both are hydrophobic. The head of the molecule acts as a solar panel, facing and absorbing light.

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.
