The cell wall may be enclosed by another thick capsule made of. Some types of cells (especially the cells of xylem tissues) consist of cellulose and lignin and these provide additional rigidity and waterproofing. This is because each cell type answer:
Cell walls protect the cells from damage.
Prokaryotic cells have a cell membrane, and one or more layers of additional protection from the outside environment. This extracellular matrix is characteristically absent from animal cells, although animal cells have extracellular matrix components on their surface. Which cell type has a thick and lignified cell wall? Different cell types can look wildly different, and carry out very different roles within the body.
