Which organelle in plant cells contains chlorophyll and is the site of photosynthesis?
A. Vacuole
B. Chloroplast✓ Correct Answer
C. Lysosome
D. Centrosome
💡 Solution & Explanation
Chloroplasts are specialized double-membrane organelles found in plant cells that contain chlorophyll pigments necessary for absorbing solar energy during photosynthesis. Unlike vacuoles that store cellular sap or lysosomes that handle intracellular digestion, chloroplasts act as the primary site for converting light energy into chemical energy. This photosynthetic capability forms the energetic foundation for nearly all terrestrial food webs.
