Question

The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents what?

Answer 1

dehydration

Most prokaryotes have a peptidoglycan cell wall and many have a polysaccharide capsule  Figure 4.5 . The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion. Pili are used to exchange genetic material during a type of reproduction called conjugation. Fimbriae are used by bacteria to attach to a host cell.
