Cell structure Functions
Capsule Protect the cells from engulfment by eukaryotic cells, such as macrophages.
Cell wall Determines the shape of the cell and provide structural support.
Cytoplasmic membrane It interacts with the outside world as it is semi-permeable in nature.
Nucleus It directs and controls all the cellular activities.
Mesosome It helps to increase the surface area of the plasma membrane.
Spore They help in the reproduction of the organism and can withstand the adverse environment.
Flagellum It helps in locomotion by causing movement in the surrounding fluid.
