Permeability for me is like a door, it can allow things in but it can also block bootlegging things enter to the cell.

A selective permeable cell membrane is what lets specific molecules to go through. Phospolipids are the basic structure of a cell membrane. The basic structures of a fluid mosaic model are cholesterol, glycoproteina, and glucolipids. Phospolipids are important because they are the fats in a cell. They are composed of carbon and oxygen. They have a charged head while the tail has no charge. Proteins allow things to get across because of its large amounts of carbon, the aquaporin and the cell wall also has a great part on this.

Selective permability is the ability to let things in and out of the cell. The cell membrane contains proteins and phospholipids the mosaic model is basically the animal cell model. What is unique about the phospholipid is that unique other organelles the head likes water and the tails hydropobic. They would be osmosis diffusion and aquaporin

1) Selective Permeability is a cell membrane that lets certain molecules pass through it. How I remember this is I feel like my mind is a cell membrane I let some things go in like what is good (math,science,reading) and don't let the negative things pass.
