GENERAL HISTOLOGY

Detailed explanation-1: -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-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: -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: -Chloroplasts are specialized for photosynthesis and are unique in that they contain the internal thylakoid membrane system.
