HORTICULTURE

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: -Chloroplasts contain green pigment called chlorophyll which helps in manufacture of food through the process of photosynthesis. Since, animals do not manufacture food so they do not need chloroplast. And hence, chloroplast is found only in plant cell.

Detailed explanation-3: -It is a common perception that animal cells do not have chloroplasts, the organelles that performs photosynthesis. Yet, a small number of sea slugs are able to incorporate carbon from CO2 by performing photosynthesis using sequestered chloroplasts from the macroalgae in their diet.

Detailed explanation-4: -Chloroplasts are found in all green plants and algae. They are the food producers of plants. These are found in mesophyll cells located in the leaves of the plants. They contain a high concentration of chlorophyll that traps sunlight.
