HORTICULTURE

Detailed explanation-1: -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-2: -Commonalities of energy processing in both plants and animals have become even stronger by the finding that chloroplast can be found in animal cells. The discovery of kleptoplasty, a functional chloroplast in cells of a non-photosynthetic host [28] is a remarkable phenomenon [28–31].

Detailed explanation-3: -In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Detailed explanation-4: -Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria. Both plant and animal cells have vacuoles.

Detailed explanation-5: -The plant cells that make up the roots and/or tubers typically do not contain chloroplasts since it would be useless to have them. Chloroplasts are mainly found in the leaves tissue, which explains why most of them are green. Stems also contain chloroplasts but not as much as the ones contained in the leaves.
