Question

Name the three major functional regions of cells. Briefly mention the components of each and explain the
function of each​

Answer 1

There are three major functional regions of cells: cell membrane or plasma membrane, nucleus and. cytoplasm.

The major components of a cell membrane are phospholipids, glycolipids, proteins, and cholesterol. The cell membrane contains more protein by mass, but the molar mass of a protein is about 100 times that of a lipid. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

The three major elements of the cytoplasm are the cytosol, organelles and inclusions.
unction of Cytoplasm. The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts.


Nucleus is covered by a membrane called nuclear membrane and includes numerous components Significant components of nucleus are nucleoplasm, chromatin and nucleolus. This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
