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 are only found in plants, algae, and three species of amoeba – Paulinella chromatophora, P.

Detailed explanation-3: -However, not all parts of a plant structure are suitable to do this, so not all types of plant cells contain chloroplasts. The plant cells that make up the roots and/or tubers typically do not contain chloroplasts since it would be useless to have them.

Detailed explanation-4: -Chloroplasts are found in the cells of all green and algal tissues. Chloroplasts can also be found in non-green photosynthetic tissues, such as the brown blades of gigantic kelp or the red leaves of certain plants.

Detailed explanation-5: -Chloroplasts are disc-shaped organelles found in the cytosol of a cell. They have outer and inner membranes with an intermembrane space between them.
