Detailed explanation-1: -Plasma Membrane: The bacterial plasma membrane is composed primarily of protein and phospholipid (about 3:1). It performs many functions, including transport, biosynthesis, and energy transduction. Organelles: The bacterial cytoplasm is densely packed with 70S ribosomes.
Detailed explanation-2: -Bacteria have a well-defined cell wall composed of peptidoglycan. It protects the bacteria from outer environment and can also confer pathogenicity. Gram-negative bacteria have two layers of cell walls, one inner peptidoglycan layer, and one outer lipopolysaccharide layer.
Detailed explanation-3: -A bacteria is made up of a single cell. Such organisms are called single-celled organisms.
