The cell has a phospholipid membrane with other molecules interspersed throughout. However, phospholipid is the major player. It is a molecule with a lipid (fat) tail and a phosphate head. The molecules orient themselves, due to hydrophobic interactions so that there is a double row of phosphate with tails of lipid facing toward each other. This allows the membrane to interact with both the cellular and extracellular space, which are both watery, and provide some regulation for what enters and exits the cell.

What 2 main group of organic materials make up the plasma membrane of a cell?
The main organic materials that make up the plasma membrane of a cell are lipids and proteins. Lipids, such as phospholipids and cholesterol, form the basic structure of the membrane, providing a barrier to the cell's interior. Proteins are embedded within the lipid bilayer and facilitate various functions, including transport of molecules and cell signaling.

Which two organic molecules make up the cell membrane?
Phospholipids and cholesterol are the two main organic molecules that make up the cell membrane. Phospholipids form a lipid bilayer that provides structural integrity, while cholesterol helps maintain the fluidity and stability of the membrane.
What are the three parts that make up most cells?
The three main parts that make up most cells are the cell membrane, which surrounds and protects the cell; the cytoplasm, which is a jelly-like substance inside the cell where organelles are located; and the nucleus, which contains the cell's genetic material (DNA).
What three parts make the egg a cell?
An egg is a cell itself, consisting of three main parts: the cell membrane (outer layer that encloses the cell), cytoplasm (gel-like substance inside the cell), and the nucleus (contains genetic material).

What is the connection between lipids and proteins to the cell membrane?
Lipids make up the main structural component of the cell membrane, forming a lipid bilayer that gives the membrane its flexibility and impermeability. Proteins are embedded within this lipid bilayer, serving various functions such as cell signaling, transport of molecules, and structural support. Together, lipids and proteins work in harmony to maintain the structure and function of the cell membrane.
What chemical structure make up the cell the membrane?
The main component of the cell membrane is phospholipids. These are molecules with a polar (hydrophilic, water-loving) head composed of a phosphate (and usually a choline) and a non-polar (hydrophobic, water-hating) tail composed of fatty acids. In the cell membrane, these phospholipids are arranged in a bilayer - with heads facing the outside and the tails facing each other in the center of the membrane.
What controls what enters and leaves the cell?
IT depends on what cell. In the plant cell it is the cell wall and the cell membrane. But in the animal cell it is only the cell membrane.
What 2 thing make up the cell membrane?
The cell membrane is primarily composed of lipids (such as phospholipids) and proteins. These two components work together to control the passage of substances in and out of the cell, maintain cell structure, and facilitate cell communication.
