Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which cell structures are only found in plant cells?
A
Ribosomes and Cell Wall
B
Cell Wall and Vacuole
C
Cytoplasm and Chloroplast
D
Cell Wall and Chloroplast
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. Plant cells are rigid and have a hexagonal shape because of the presence of cell wall.

Detailed explanation-2: -Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

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: -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.

Detailed explanation-5: -Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
