A double layer, known as a bilayer, of phopholipids forms the main part of the cell membrane.
phospholipids
Phospholipids are the most abundant molecules in the cell membrane. They have a hydrophilic head and hydrophobic tails that arrange themselves in a lipid bilayer to form the basic structure of the membrane.
If you are referring to a cell as in a biological cell.. animal cells are shaped by their cell membrane. They don't really have a set shape exactly, because the membrane is made up of flexible lipids. plant cells are more structured, in addition to a cell membrane, they have a cell wall. This much more rigid then the membrane. If you were looking for different information,. I hope you find out :)
The outer covering of an animal cell is the cell membrane. The outer covering of plant cells is the cell wall, which is much stronger and stiff.
it is not call ed the outer membrane, its the cell wall. It does the same thing like the cell membrane, but the cell wall is much for stricter with objects coming in and out of cell, what is call, selectivly permeable
No, in fact most of the cell membrane consist of phospholipids and proteins. Integral proteins are mostly used for transport and other functions and the phospholipids which have a polar phosphate head and nonpolar lipid (fat) tails.
Cell Wall
Phospholipids are the primary molecules that make up cell membranes. They have a hydrophilic head that faces outward toward the watery environment and two hydrophobic tails that cluster together in the middle of the membrane. Other components, like proteins and cholesterol, also contribute to the structure and function of the cell membrane.
its is a permeable membrane which allows osmosis and diffusion of small molecules such as glucose, salts and mineral ions. In an animal cell, it cannot hold the cell turgid like plant cells can, and so it bursts when too much water has entered it. This is osmotic shock
They do not differ much. The proteins in each are slightly different.
