Membranes of the grane are sites where?
Correct answer: C. Sunlight is trapped
- A. Oxygen is stored
- B. Food is stored
- C. Sunlight is trapped
- D. CO2 is stored.
Explanation
The membranes of grana contain chlorophyll and other photosynthetic pigments arranged in photosystems. These pigments absorb sunlight and convert its energy into chemical energy during the light-dependent reactions. Students may choose b because chloroplasts ultimately help make food, but food production is not the direct function of the grana membranes.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
