Origin of Cell Wall in Plants | Botany

In this article we will discuss about the origin of cell wall in plants. Initially middle lamella creates a new boundary between the two-daughter nuclei of a dividing cell. The components of cell wall deposit on either side of middle lamella to form the cell wall. In a non-vacuolated cell, nucleus is usually present at the centre where it divides. [...]

Growth of Cell Wall in Plants | Botany

Growth of cell wall involves the growth in surface area as well as growth in thickness. Normally, the entire cell wall grows. Localized growth occurs in fibres, root hairs, tracheids and pollen tubes. A new primary wall grows in surface area. The wall expands due to the turgor pressure exerted on the walls by the protoplast. Turgor pressure is developed [...]

Biochemical Pathways of Major Wall Component Formation | Plant Cell

In this article we will discuss about the three main biochemical pathways of major wall component formation. The biochemical pathways are: 1. Polysaccharides 2. Protein 3. Lignin. Biochemical Pathway # 1. Polysaccharides: They are synthesized from sugar nucleotides by polysaccharide synthases (Glycosyltransferase). The monosaccharides glucose, galactose, mannose, xylose, arabinose, glucuronic acid, galacturonic acid and fucose etc. compose the wall polysaccharides. [...]
