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.
Plant cells have a cell wall, which is made of cellulose and helps it maintain rigidity.
The cell wall, composed of cellulose, is the structure that makes plant cells more rigid than animal cells. It provides support and protection to the plant cell, helping maintain its shape and structure.
No some types of bacteria do not have cell walls
who
Plant cells have a rigid cell wall made of cellulose that provides structural support, while animal cells do not have this feature. The cell wall allows plant cells to resist osmotic pressure and maintain their shape, giving them a more rigid structure compared to animal cells.
There is a cell membrane in both; however, plant cells have "walls" which are a little more rigid.
Plant cells have rigid cell walls made of cellulose that provide structural support and protection, preventing them from being pinched in two. Animal cells do not have a cell wall and are more flexible, allowing them to be pinched or deformed to some extent.

The Mitochondria
Animal cells do not have a cell wall, while plant cells do. Plant cells typically have chloroplasts for photosynthesis, while animal cells do not. Animal cells can move and change shape more easily due to their flexible membrane, while plant cells are typically more rigid due to their cell wall.
Bacteria cells are prokaryotic and lack a nucleus or membrane-bound organelles, unlike plant and animal cells which are eukaryotic. Bacteria cells are typically smaller and simpler in structure compared to the more complex plant and animal cells. Additionally, bacteria cells have a cell wall made of peptidoglycan, while plant cells have a cell wall made of cellulose and animal cells do not have a cell wall.
No, blood cells do not have cell walls. Red blood cells have a flexible membrane to allow them to squeeze through small blood vessels, while white blood cells have a more elastic membrane to change shape as needed to engulf pathogens.
