Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What structures distinguish a plant cell from an animal cell?
A
Plant cells have cell walls and ribosomes.
B
Plant cells have cell walls and chloroplasts.
C
Plant cells have chloroplasts and ribosomes.
D
Plant cells have chloroplasts and mitochondria.
Explanation: 

Detailed explanation-1: -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-2: -Animal Cells versus Plant Cells Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Detailed explanation-3: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

Detailed explanation-4: -Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.

Detailed explanation-5: -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.
