It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily.
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
selective permeability
gases such as oxygen and carbon dioxide
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.
Selective Permeability
Selective Permeability
Plasma membrane permits the entry and exit of some materials in the cells. Therefore, the plasma membrane is called a selective permeable membrane. Functions of plasma membrane : 1) Diffusion 2) Osmosis 3) Mediated transport

Selective permeability
Because it is a semi permeable membrane IE. it only allows selective particles to go inside it and outside it.
Yes, it is selective about the compounds and molecules it allows across the membrane.
