Which organelle is typically especially numerous in photosynthetic leaf mesophyll cells because it captures light energy and fixes carbon?
A.Lysosome
B.Chloroplast
C.Centriole
D.Nucleolus
Explanation
Core Concept
Leaf mesophyll cells generally contain many chloroplasts, where the light reactions and carbon-fixation reactions of photosynthesis occur. 'Especially numerous' is defensible; 'most abundant organelle' was undefined because abundance could mean number, volume, or another metric.
Correct Answer
BChloroplast
