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.

What are the three main parts of cells?
A cell consists of three main parts---the nucleus, the cell "stuff" called cytoplasm, and the outer cell membrane.
What are the 3 major parts of cell?
cell membrane, cytoplasm, and organelles
What three cell parts do all cells have in common?
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.
Two activities of the cell membrane are?
The cell membrane regulates what substances can enter and leave the cell through its selective permeability. It also helps maintain the cell's shape and structure by providing support and protection.
What three polymers are in the cell membrane?
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.
What are three types of compounds in the cell membrane?
cellulose, cell wall, cell membrane
What are three things found in a plant cell that are not found in an animal cell?
A Cell Wall.
What are the three main part of a cell?

What are the three parts of a cell and what there jobs are?
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
The three parts of a cell are the cell membrane cytoplasm and?
Nucleus
What are the three jobs of the cell wall?
The three jobs are: Maintain the shape of the cell; Protect the cell; Prevent bursting due to turgor pressure.
What are two jobs of cell membrane?
protect a cell regulate what goes in and comes out
What three parts does EVERY cell have?
cell membrane, cytoplasm, and DNA
