PATHOLOGY

Detailed explanation-1: -In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Detailed explanation-2: -The palisade layer contains the most chloroplasts as it is near the top of the leaf. The chloroplasts contain the pigment chlorophyll. The palisade cells are arranged upright.

Detailed explanation-3: -Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.

Detailed explanation-4: -In which part of a plant would you expect to find the most chloroplasts and why? Leaves because they make photosynthesis.
