The Three Major Parts of a Cell Are

Question

The three major parts of a cell are
A)the endoplasmic reticulum, Golgi apparatus, and vesicles.
B)the nucleus, nucleolus, and nuclear envelope.
C)microtubules, ribosomes, and centrosomes.
D)the nucleus, cytoplasm, and cell membrane.

Accepted Answer

The three major parts of a cell are the nucleus, cytoplasm, and cell membrane. The nucleus contains the genetic material and controls the cell's activities, the cytoplasm is the jelly-like substance that fills the cell and contains organelles such as mitochondria, ribosomes, and the endoplasmic reticulum, and the cell membrane surrounds the cell and regulates the movement of substances in and out of the cell. Microtubules, ribosomes, vesicles, centrosomes, Golgi apparatus, and nucleolus are all important cellular components, but they are not the three major parts of a cell.
