What are the different parts of the human cell?


Expert Answer

Step 1

The cell is known as the smallest structural as well as the functional unit of all living organisms. The human body possesses over a trillion cells. These cells form the organ system in the human and are responsible for the functions of all organs in the body.

Step 2

The different parts of the cell are plasma membrane, cytoplasm, and nucleus. The plasma membrane or cell membrane is a thin membrane, which covers the cell. It is composed of a lipid bilayer. It separates the interior region of the cell from the external environment. The main function of the plasma membrane is to regulate the movement of various substances in and out of the cell. It is selectively permeable to some substances, for examples, organic molecules and ions. It facilitates the transport of several materials, which are required for the survival of the cell.

Step 3

The cytoplasm is present between the regions of the plasma membrane and the nucleus. It is composed of cytosol and organelles. The presence of the aqueous component or a viscous fluid in the cytoplasm of the cell is called the cytosol. Several intracellular organelles and other particles are suspended in the cytosol. The cytoplasm contains various important organelles, such...
