The cell wall is present in prokaryotes, microorganisms, unicellular organisms, molds and bacteria.īacterial cell walls are defined by the existence of peptidoglycan, whereas Archaea cell walls are void of this chemical. The cell wall acts as a storage site for signal proteins & regulates the molecules that detect the existence of pathogenic microbes and contaminants.It serves as a restrictive component from which leaves and stems can develop.

It provides a highly absorbent channel for the circulation and distribution of water, minerals and other tiny nutritional molecules.It acts as a buffer between a cell and its outer environment The cell wall offers complete protection for a living cell from its surroundings.The functions of the cell wall are as follows: It provides additional stability and protection to the cell while also acting as a filtering framework.

It can be hard, adaptive and even restrictive at times. Meaning of the Cell WallĪ cell wall is a compositional structure covering some cells external to the cell membrane. The cell wall’s primary function is to provide support and rigidity to the cell and filter molecules that enter and exit the cell. The cell wall is a plant cell’s defensive, semi-permeable outermost layer. However, it consistently performs many essential tasks for plant life.Ī cell is the fundamental part of an organism that comprises a set of that organism’s elements. The cell wall is commonly regarded as an unresponsive system that meets primarily mechanical and structural functions. One of the many features that distinguish plant cells from animal cells is the cell wall.
