Hello mate,
Here is your answer:-
1.The plasma membrane is a fluid mosaic. This means that it is flexible and made up of many different types of molecules. Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent.
2.The cell membrane or the plasma membrane is known as a selectively permeable membrane because it regulates the movement of substances in and out of the cell. This means that the plasma membrane allows the entry of only some substances and prevents the movement of some other materials.
*CO2 is removed from the cell by the process of diffusion.
*Diffusion is important as it allows cells to get oxygen and nutrients for survival. In addition, it plays a role in cell signaling, which mediates organism life processes.Diffusionis important for several reason are ; it promotes cellular respiration - In order forcells to survive, they need oxygen.
3.The cell wall provides mechanical support to the cell.
