Which specialized cell organelle found in plants and algae contains chlorophyll and serves as the primary site for the light reactions of photosynthesis?

💡 Solution & Explanation

Chloroplasts contain internal thylakoid membranes embedded with chlorophyll pigments that absorb solar radiation to initiate the light-dependent reactions of photosynthesis. Mitochondria are responsible for cellular respiration and ATP synthesis rather than light energy absorption, whereas Golgi bodies process and package cellular proteins. Plant cell organelle functions are a staple topic in biology syllabi for public service commissions.
