Structure organisation & function of plant cell wall

Abstract

The strong outer shell that serves to protect the plant cell is called the cell wall, and it is present in all plant species. Pectin, cellulose, and hemicellulose are the three primary types of polysaccharides that make up the cell wall. Carbohydrates make up the majority of the cell wall. In addition to these, there are phenolic and aliphatic polymers, which play an essential role as structural proteins. In addition to providing the plant body with the mechanical strength necessary for upright growth and the formation of structures, the cell wall also plays important roles in the processes of the cell itself, including cell expansion, tissue differentiation, intercellular communication, the movement of water, and defensive responses against pests or pathogens. It is also possible that cell walls have a role in signal detection during the pattern creation stage of plant growth.
