Detailed explanation-1: -Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant’s life style.

Detailed explanation-2: -Plant Cell Structures The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin, which makes it more rigid. The cell wall shapes, supports, and protects the cell.

Detailed explanation-3: -A cell wall is a firm structure that encloses the cell membrane of a cell, giving it form and protection. Because the plant cell wall is made of cellulose, plant cells have firm and rigid shapes and are able to create very strong and tall structures. Plants are the only organisms that have cell walls made of cellulose.

Detailed explanation-4: -Cell walls are the rigid outer covering layer of the plant cell. It is made up of cellulose and polysaccharides that makes it tough and gives rigidity to plant cells. This is the reason that plant cells remain more rigid than animal cells.
