NURSING ANM AND GNM

Detailed explanation-1: -Cell Wall-Each bacterium is enclosed by a rigid cell wall composed of peptidoglycan, a protein-sugar (polysaccharide) molecule. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment.

Detailed explanation-2: -Examples of Prokaryotic Cells Bacteria have some unique structures such as pili, flagella and capsule. They also possess extrachromosomal DNA known as plasmids.

Detailed explanation-3: -Cell Structure Prokaryotes have a nucleoid (nuclear body) rather than an enveloped nucleus and lack membrane-bound cytoplasmic organelles.

Detailed explanation-4: -All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface. Flagella and some pili are used for locomotion, fimbriae help the cell stick to a surface, and sex pili are used for DNA exchange.
