Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which structures are found in plant cells, but not in animal cells?
A
Cell membranes and mitochondria
B
Vacuoles and cholorplasts
C
Cell walls and cytoplasm
D
Chloroplasts and cell walls
Explanation: 

Detailed explanation-1: -Final answer : The two structures found in plant cells that are absent in animal cells are cell wall and chloroplast.

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. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.

Detailed explanation-3: -Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls. Was this answer helpful?

Detailed explanation-4: -Plant cells must be rigid to maintain their posture, and they require chlorophyll, which is found in the chloroplast, for food production. Animals, on the other hand, do not require cell rigidity and do not have chloroplast because they are heterotrophs.

Detailed explanation-5: -Which of the following is found in a plant cell but not in an animal cell? The answer is a. chloroplast. Chloroplast is an organelle normally found within plant cells and some algae that undergo photosynthesis.
