It Is Basically Cells
The Cell Membrane forms the outside boundary that separates the cell from its environment.
The cell membrane is a semi-permeable membrane that forms a boundary between the cell and the external environment. The vacuole is the storage area within the cell.
The answer is proteins.
In cells without a cell wall, the outside boundary that separates the cell from its environment is formed by the cell membrane or plasma membrane. This phospholipid bilayer regulates the passage of molecules in and out of the cell, allowing for selective permeability.
Cell membrane
The lipid that forms the framework of the cell membrane are phospholipids. Phospholipids are composed of two fatty acids, a glycerol unit, a phosphate group, and a polar molecule.
This molecule is ATP (Adenosine Triphosphate), a nucleoside.
Phospholipids are the primary type of molecule that forms the cell membrane. They have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails, allowing them to arrange in a bilayer to create the cell membrane.
