Question

Which of the following is absent in animal cell?

• A. Cell wall and plasma membrane
• B. Mitochondria
• C. Centrioles
• D. Cell wall and chloroplast

Answer 1

The correct option is D Cell wall and chloroplast

Cell wall and chloroplast are not present in the animal cell. The cell wall in a plant cell is a very tough, flexible and sometimes fairly rigid layer that surrounds some types of cells. It surrounds the cell membrane and provides these cells with structural support and protection. In addition, the cell wall is acting as a filtering mechanism.

Chloroplasts are exclusively found in plants and photosynthetic unicellular organisms and, hence, animal cells lack chloroplast.
