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 # [...]
Plasmodesma (plural: plasmodesmata) is thin irregular cylinder of cytoplasm lined by plasmalemma, passing through fine pores in the cell walls, thus forming a connection between the cytoplasm of adjacent cells. They are found in higher plants and fluctuate widely in abundance and distribution. They are commonly present in primary pit fields and pit membranes of young and mature living cells [...]
The cell wall is mainly composed of carbohydrate rich materials. The major components of cell wall are cellulose, pectins, hemicelluloses, proteins and phenolics. The cell wall is a biphasic structure consisting of relatively rigid cellulosic microfibril embedded in gel-like non-cellulosic matrix. The microfibrillar phase consists of only cellulose (β1, 4-glucan) and the matrix is composed of non-cellulosic polysaccharides and other [...]
