It is important to note that,population continues to decrease in rural areas and increase in urban areas.This is attributed to certain factors that are pushing people out of r â¦ ural areas and pulling them to the urban centers.
1 The outer surface of cells is often covered in a polysaccharide or protein material called glycocalyx. 2  Glycocalyx can be formed from protein, polysaccharides, polyalcohols or amino sugars.3  Glycocalyx can function in attachment, protection from desiccation, and protection from attack by a hosts immune system.he general term for any network of polysaccharide or protein containing material extending outside of the cell is the glycocalyx. Many bacteria produce such a coating on the outside of their cell, and they come in two types: capsules and slime layers. The difference between the two is somewhat arbitrary.
Glycocalyx: The glycocalyx, an extracellular polymer that surrounds the outside of the cell, is called the capsule when firmly attached; when loosely attached, itâs called a slime layer. The capsule protects bacteria from being phagocytosed (taken up) by immune cells.ere is a list of structures important to prokaryotic cells. Nucleoid: The nucleoid is the region in the cell where the tangled mass of genetic material, called the chromosome, is found. Unlike the nucleus of eukaryotic cells, the nucleoid does not have a membrane.
