Explanation:
Detailed explanation-1: -What Is the Cell Wall? A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary cell wall, the middle lamella, and the secondary cell wall (not pictured).
Detailed explanation-2: -Algae, fungi, and plant cells have a cell wall; animal cells and protozoans lack cell walls. The rigid, tightknit, polysaccharide molecular structure of the cell wall helps the cell resist osmotic lysis.
