. Define the term

i. Cell structure

ii. Mucilage 

Best Answer


A bacterial cell is covered by mucilage. The cell is differentiated into cell wall, plasma membrane, cytoplasm, nucleoid, plasmids, flagella, pili and fimbrie. Mucilage, cell wall and plasma membrane are together called cell envelope.

Mucilage (Glycocalyx)

It is the outermost coat of bacterial cells which is rich in polysaccharides. A loose sheath is called slime layer while a thick (more than 0.2  ) and tougher mucilage is called capsule. It protects the cell against the desiccation and viral attack.
