yes, they do
Collenchymatous cells have rigid cell wall
Plant cells have rigid cell walls composed of cellulose that provide structural support and protection. Animal cells do not have cell walls but instead have flexible cell membranes that allow for mobility and shape changes. The presence of cell walls in plant cells is essential for withstanding the pressure of water entering the cell.
Mammal cells do not have cell walls. Although bones are hard and rigid, they do not have cell walls. The only cells that possess a cell wall are plant cells.
Animal cells lack rigid cell walls and chloroplasts.
Not at all. In fact, animal cells don't have cell walls at all. Plant cells are the ones with rigid cell walls in order to keep from bursting opening when it's central vacuole is full of water.

the cell walls box like shape
Animal cells lack rigid cell walls and chloroplasts.
Rigid cell walls and chloroplasts spring to mind.
Plant cells have rigid cell walls made of cellulose to provide support and structure to the plant. Animal cells, on the other hand, do not need rigid cell walls because their shape and structure are maintained by their cytoskeleton and extracellular matrix. Additionally, animal cells need more flexibility for movement and other cellular functions which would be restricted by a rigid cell wall.
They do not seem more rigid, they are more rigid! They both have cell walls. Many eubacteria, the bacteria you are most familiar with, have cell walls of peptidoglycan. Plants have cell walls made of interlocking cellulose.
No some types of bacteria do not have cell walls
