CELL STRUCTURES: PROKARYOTIC & EUKARYOTIC CELLS

667 WD

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types, gram positive and gram negative. Out of all the structures, the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical, spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan. The cell- wall helps the bacterial cell to survive at a greater degree, as an independent unicellular organism. This provides protection to the cell from the turgor pressure, which is raised due to an increased level of protein concentration in the cells. The cell- wall is very important because it determines the shape of the particular cell (Bacterial Cell Structure, 2009).
