Detailed explanation-1: -Chloroplasts are double-membraned organelles present only in plant cells. Lysosomes, ribosomes and mitochondria are present in both plant and animal cells.

Detailed explanation-2: -The organelles found only in plant cells include chloroplast, cell wall and a vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.

Detailed explanation-3: -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-4: -Chloroplasts are specialized for photosynthesis and are unique in that they contain the internal thylakoid membrane system.

Detailed explanation-5: -Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
