C ell found various components with specific Function These components include- cell wall cell membrane cytoplasm nucleus and cell organelles etc.

Fluid pliableeasily moved - due to lipid component -phospholipids can move laterally b. Membranes also exist within cells forming various. The cell membrane is kind of like a soap bubble.

Proteins and lipids are the major components of the cell membrane. The Plasma membrane is a thin bi- layered structure which surrounds each cell consists of lipids phospholipids 75 cholesterol 20glycolipids 5 proteins partially or completely embedded carbohydrates etc 6-10 nm thick. Cellular membranes are fluid mosaics of lipids and proteins Phospholipids are the most abundant lipid in the plasma membrane Phospholipids are amphipathic molecules containing hydrophobic and hydrophilic regions The fluid mosaic model states that a membrane is a fluid structure with a mosaic of various proteins embedded in it.
