Higher – Cell Membrane Models

This week we have been learning about the structure of the cell membrane and cell wall. Here are some of the class’s efforts.

Cell Membrane Model

Cell Wall Model 

Good effort overall. Remember the phospholipids and proteins which work together to make the cell membrane. Hydrophilic phosphate heads and hydrophobic lipid tails, together make the phospholipids.The cell membrane is often described as a fluid mosaic. Fluid because of the constant movement of the phospholipids and mosaic because of the large and small parts of the membrane which are arranged randomly.The cell membrane is arranged as a bilayer of phospholipids with proteins interspersed throughout. It is selectively permeable, allowing some molecules such as oxygen and water to pass through. The cell wall is fully permeable and made of cellulose fibres which are slightly elastic.
