Cytoplasm contains which of the following components?

• A. Nucleus and chromatin
• B. Cytosol and organelles
• C. Plasma membrane and cytosol
• D. DNA and RNA

Answer: (B)

The cytoplasm is made up of cytosol and the organelles. The cytosol is the clear, jelly-like fluid inside the cell that suspends everything and contains water, ions, and dissolved molecules. The organelles are specialized structures such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and more, each carrying out distinct functions essential to the cell’s activities. This combination of fluid and internal machinery defines the cytoplasm.

Nucleus and chromatin stay inside the nucleus, not in the cytoplasm. The plasma membrane surrounds the cell and is not part of the cytoplasm’s interior contents. DNA and RNA are nucleic acids found mainly in the nucleus (with some RNA in the cytoplasm during protein synthesis) and are not the defining components of cytoplasm.
