On which of the following component of chloroplast chlorophyll is arranged?
Correct answer: C. Thylakoids
- A. Cell membrane
- B. Matrix
- C. Thylakoids
- D. Stroma
Explanation
Chlorophyll is embedded in the photosynthetic membranes of thylakoids, where it captures light energy for the light-dependent reactions. The stroma contains enzymes for carbon fixation but does not arrange the chlorophyll molecules into the light-absorbing membrane system. A student may choose stroma because it is also a major chloroplast component, but chlorophyll is associated with thylakoid 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.
