Which structure would you expect to be abundant in plant cells due to its role in photosynthesis?

• A. Chloroplasts
• B. Mitochondria
• C. Ribosome
• D. Lysosome

Answer: (A)

Photosynthesis happens in chloroplasts, which contain the light-absorbing pigment chlorophyll and organize the light-dependent reactions and the Calvin cycle. Plant cells, especially leaf cells, have many chloroplasts to capture light energy efficiently and convert it into chemical energy (glucose). Mitochondria are the energy-powerhouses for respiration, but they’re not the site of photosynthesis. Ribosomes and lysosomes have other roles and aren’t abundant because of photosynthesis.
