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 mature tissues, spaces frequently occur between cells. These spaces are known as intercellular spaces. The spaces may be small, large (ex. Canna)—called chambers and elongated—called canals. The spaces may be considerably elongated in one plane—called duct. The spaces are exceptionally well developed in aerenchyma of many aquatic plants. They form a connected system throughout the entire plant body. The [...]
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. [...]
