Which of the following that best describes an animal cell?

a. centrosomes are absent

b. cell wall is absent

c. mitochondria are present but fewer

d. is triangular

Answer: B. cell wall is absent

Explanation:

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.

Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones.
