2 layers of lipids.
A cell membrane consists of two layers of phospholipids, making it a double-layered structure. This double layer is known as a lipid bilayer.
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
If the cell membrane were made of only polar substances, it would likely be unable to form a stable bilayer. Polar molecules would not effectively create a hydrophobic core, which is essential for membrane integrity and function. As a result, the membrane would be permeable to many substances, leading to uncontrolled movement of ions and molecules, ultimately compromising the cell's ability to maintain homeostasis and perform necessary functions.
The membrane of a cell is like your skin in the fact that both are outer layers that control what goes into and out of the center of the object. The cell membrane controls what moves in and out of a cell and your skin controls what moves in and out of your body (sort of, the differences get greater the more closely you look at the two, but that is the basic similarity). In a nutshell, they both are gate keepers that control an internal environment.
There is typically one cell membrane in each cell. The cell membrane, also known as the plasma membrane, is a thin semi-permeable barrier that surrounds the cell and controls the movement of substances in and out of the cell.

There are 2, surrounding a water layer.
the cell membrane, also known as the plasm membrane, forms a boundary between a cell and the enviroment and is made of a double layer of phospholipids. A phospholipid is made of a charged phosphate group, a glycerol, and two fatty acid chains.

A cell has a nucleur membrane but it also has mas many other "mini organs". you can look up cell diagram to see them all.
Two phospholipid layers? I think.
The primary molecule of the cell membrane is a phospholipid. Phospholipids have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, which allows them to form a double layer in the cell membrane called the phospholipid bilayer.
