CELL MEMBRANE- Cell Membrane is a Thin, Elastic, Delicate and Selective permeable membrane found around all kind of cell (Prokaryotic and Eukaryotic cell).
Biochemical estimation reveals that biomembrane is formed of Lipid(phospholipid) , protein and Carbohydrate.
Davson and Daniell proposed sandwich model
According to this model cell membrane is like a sandwich ,as in sandwich between two bread piece salad is placed. Same thing occurs in cell membrane here phospholipid(bilayer) placed between two layers of protein. Size of protein is 2*20= 40 angestrom
Size of phospholipid(bilayer) = 35 angestrom
Thus total width of cell membrane is 75 angestrom. It can vary upto 100 angestrom.
