1)It gives protection to the cell.
2)It prevents the internal environment of the cell from exposing to the external environment.
3)It allows the exchange of certain selective materials from the external environment of the cell into the cell and vice versa such as oxygen and carbondioxide.
4)In some unicellular organisms like amoeba, the flexible cell membrane allow to engulf in food particles and expel waste matter. This process is called endocytosis.
A cell consists of three main parts---the nucleus, the cell "stuff" called cytoplasm, and the outer cell membrane.
All cells have three common features: a cell membrane (plasma membrane) that encloses the cell and controls what enters and exits, cytoplasm where cellular activities occur, and DNA that serves as the genetic material and contains instructions for cell function.
cell membrane, cytoplasm, and organelles
The three main polymers in the cell membrane are phospholipids, cholesterol, and glycolipids. Phospholipids form the lipid bilayer structure, cholesterol helps regulate membrane fluidity, and glycolipids are involved in cell recognition processes.
Nucleus, Cell Membrane, and CytoplasmThe three main parts of a cell are the nucleus, cytoplasm, and plasma membrane. The nucleus is the control center of the cell. The cytoplasm is the fluid within the cell. The plasma membrane completely surrounds the cell and controls what can enter and exit the cell. For more information look at the related link below.

A cell consists of three main parts---the nucleus, the cell "stuff" called cytoplasm, and the outer cell membrane.
the 3 parts of a cell are : 1 Nucleus- this controls what happens inside the cell . 2 Cell Membrane - this controls what substances enter and leave the cell 3 Cytoplasm - this is where the chemial processes occur
Nucleus
The three jobs are: Maintain the shape of the cell; Protect the cell; Prevent bursting due to turgor pressure.
