Microbes like bacteria and many fungi can be grown on nutritive media to form colonies, that can be seen with the naked eyes. Such cultures are useful in studies on micro-organisms.

Bacteria: (a)/FigIV Rod-shaped, magnified 1500X; (b) Spherical-shaped, magnified1500X; (c) A rod-shaped bacterium showing flagella, magnified 50,000X

Viruses: (a/Fig I) A bacteriophage; (b)/Fig II Adenovirus which causes respiratory infections; (c)/FigIII Rod-shaped Tobacco Mosaic Virus (TMV). Magnified about 1,00,000–1,50,000X
