The human cell membranes are made out of lipids because lipids propel water, and if it weren't made out of liquids, every time we come in contact with water we would either shrink or grow in big amounts.
It is made up of protein and lipids
because they have the ability to repel water (hydrophobic)
The cell membrane is primarily composed of lipids, specifically phospholipids. Proteins are also present in the membrane, serving various functions such as transport and cell signaling. Nucleic acids are typically found in the cell's nucleus and are not major components of the cell membrane.
2 layers of lipids.
The cell membrane is made of the lipid bilayer which contains lipids and proteins.

The membrane is made up of a bilayer (two layers) of phospholipids.
All (mostly) membranes of the cell including those of organelles are made up of lipids, proteins and polysaccharides (like cholesterol). The lipids and proteins are called glycolipids and glycoproteins.
The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.
The Phoshpholipid are the predominant lipids of cell membrane. They can act as anchors to cell proteins. Phospholipids can also exist out of cell membrane.
Lipids that constitute the cell membrane are primarily synthesized in the endoplasmic reticulum (ER). The smooth ER is particularly involved in the production of phospholipids and cholesterol, which are essential components of the membrane. Once synthesized, these lipids can be transported to the Golgi apparatus for further processing and distribution to various cellular membranes.
Some of the lipids found in a cell membrane include phospholipids (such as phosphatidylcholine and phosphatidylethanolamine), glycolipids, and cholesterol. These lipids play a crucial role in maintaining the structure and function of the cell membrane.
