In this article we will discuss about the plant cell which is the fundamental unit of all living organisms in terms of structure and function. This will also help you to draw the structure and diagram of plant cell. History of Discovery: Robert Hooke in 1665 first discovered plant cell. The term 'cell' was coined to describe the small walled [...]
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. [...]
The following points highlight the two main forms of combial cells in plants. The forms are: 1. Storied or Stratified Cambium 2. Non-Storied or Non-Stratified Cambium. Form # 1. Storied or Stratified Cambium (Fig. 23.1B): In TLS the initials are arranged in horizontal regular file having a stratified structure. The initials are usually short and all of about the same [...]
