Which of the following is NOT a component of animal cells?

• A. Dermis
• B. Cytoplasm
• C. Nucleus
• D. Cell membrane

Answer: (A)

Animal cells have three main internal components: the cytoplasm, the nucleus, and the cell membrane. The cytoplasm is the jelly-like substance inside the cell where many metabolic processes occur and where organelles are housed. The nucleus holds the cell’s genetic material and acts as the control center for activities. The cell membrane forms the outer boundary, regulating what enters and leaves the cell. Dermis, however, is a layer of skin tissue, not a part of a cell. It’s made up of connective tissue and other structures and exists outside the cellular level. So Dermis is not a component of animal cells.
