Which organelles are unique to plant cells?
A
ribosomes
B
vacuoles
C
chloroplasts
D
centrosomes
Explanation: 

Detailed explanation-1: -The organelles found only in plant cells include-chloroplast, cell wall, plastids, and a large central 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 specialized for photosynthesis and are unique in that they contain the internal thylakoid membrane system.

Detailed explanation-4: -Chloroplast is unique to plant cells. Chloroplast contains a green pigment called chlorophyll. Chlorophyll traps sunlight and uses it to transform carbon dioxide and water into glucose.

Detailed explanation-5: -The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole-structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
