Full Answer

Bacteria cells have two main parts: the cytoplasm and cell envelope. Bacteria cells are usually classified by the structure of the cell envelope. Membrane proteins in the cytoplasmic membrane transport sugars and amino acids into the cell. A bacterial cell may or may not have exterior flagella or pili. Some bacteria obtain food through photosynthesis; other bacteria absorb food from their environment. Bacterial cells reproduce through binary fission, in which a cell doubles in size and splits in half. The process creates two identical daughter cells that can also double and split in half. The average time for binary fission is between one and four hours.
