Question

which of the following is not one of the three major components of a typical eukaryotic cell?
plasma membrane
ribosome
nucleus
cytoplasm

Explanation:

To solve this, we recall the three major components of a typical eukaryotic cell. The three major components are the plasma membrane (which encloses the cell), the nucleus (which contains genetic material), and the cytoplasm (the region between the membrane and nucleus, containing organelles). Ribosomes are organelles within the cytoplasm, not one of the three major structural components (plasma membrane, nucleus, cytoplasm).

Answer:

B. ribosome
