Because they allow the passage of water, lipids, nutrients and ions into the cell while checking large molecules and larger polar molecules. These are controlled by transport proteins in the cell membrane. Also the membrane can surround molecules and pinch off so that molecules can be transported in and out of the cell.

What is the cell membrane like in real life?
People live in towns. People are multicellular organisms consisting of trillions of cells. Each cell has a cell membrane.
What is the purpose of the semi-permeable membrane in the process of reverse osmosis?
the semi permeable membrane is important because it only allows certain things in and out of the cell. It is like a "filter" and is essential for the cell to continue life
What are the essential gases that sustain life?
Oxygen. It is essential for respiration, which is essential for life.
Do all types of cells have plasma membranes?
YES... All LIVING cells have plasma membranes. Not every cell contains cell wall, but plasma membrane is essential for the life of a cell. If the cell loses its membrane or the membrane is ruptured, the cell will lose its cellular form and all the contents of the cell would be wasted and it would not be called a cell after that.
What are proteins essential for?
Proteins are essential for Biochemistry To Proceed , and Life To Occur.

What do cell membrane do in the plant cell?
It involves in all types of transportation of all matter necessary for a cell life therefore it is also called selectively permeable membrane.

Why atmosphere essential for life?
its essential for life because of oxygen, water. and for nutrients
Is it ozone layer essential to life or harmful to life?
It is essential to life. It protects us from UV rays.
Biological membranes are normally permeable?
Although some small molecules including oxygen, water and co2 are able to diffuse through it, the phospholipid bilayer forms a barrier to most hydrophilic molecules and ions. --Biology wit physiology, Life on Earth 5th edu - Ausesrik, Byers
