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 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 specialized for photosynthesis and are unique in that they contain the internal thylakoid membrane system.

Detailed explanation-4: -Plant cells have three unique structures which set them apart from other eukaryotes, such as animal cells: the cell wall, plastids, and vacuoles.

Detailed explanation-5: -A chloroplast is an organelle that is only present in plant cells. It is a plastid that contains chlorophyll and is also where photosynthesis takes place.
