GENERAL HISTOLOGY

Detailed explanation-1: -The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.

Detailed explanation-2: -The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider. Our skeletons are inside our bodies, rather than on the outside like insects or spiders. The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin.

Detailed explanation-3: -The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection. Besides the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall.

Detailed explanation-4: -The cell wall surrounds the plant cell, providing both structure and protection. Plant cell walls are made up mostly of cellulose, and also include hemicellulose and pectin.

Detailed explanation-5: -It provides a structural framework to support plant growth and acts as the first line of defense when the plant encounters pathogens. The cell wall must also retain some flexibility, such that when subjected to developmental, biotic, or abiotic stimuli it can be rapidly remodeled in response.
