The following points highlight the top seven functions of cell wall in the life of a plant. The functions are: 1. Gives Mechanical Strength 2. Maintains Cell Shape 3. Controls Cell Expansion 4. Controls Intercellular Transport 5. Protects Against Infective Organisms 6. Cell Wall has Signalling Device against Attack of Microorganism 7. Acts as a Reservoir of Food. Function # [...]
In this article we will discuss about the ultrastructure of cell wall in plants. This will also help you to draw the structure and diagram of cell wall. The cell wall is a biphasic structure consisting of cellulose microfibril embedded in gel-like non-cellulosic matrix. The microfibrillar phase consists of cellulose (β1, 4-glucan) only and the ultrastructure of cell wall is [...]
