Detailed explanation-1: -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.

Detailed explanation-2: -The walls of neighboring plant cells, cemented together to form the intact plant (Figure 19-68), are generally thicker, stronger, and, most important of all, more rigid than the extracellular matrix produced by animal cells.

Detailed explanation-3: -Plant cells are more rigid than the animaal cell wass due to the presene of cell wall. Plant cells are made up of an inner and outer cell layer made up of cellulose and lipids.

Detailed explanation-4: -Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.

Detailed explanation-5: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.
