A Petri dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured, originally, cells of bacteria, fungi and small mosses. It was named after the German bacteriologist Julius Richard Petri (1852-1921) who invented it in 1877. To study microorganisms like bacteria and virus in detail, it is very important to get them isolated from other species. Their transparency and flat profile allows the contents to be inspected with the naked eye, magnifying glass, or low-power microscope without removing the lid.

Vented Petri dishes have a small lip on the top edge of the dish that allows the lid to sit a little up from the bottom, allowing for some air flow. It makes it possible to inoculate and grow dozens or hundreds of independent cultures of dozens of samples at the same time. Keep the methods of using a petri dish in mind and conduct your experiment. [19][20], Petri dishes can be used to visualize the location of contamination on surfaces, such as kitchen counters and utensils,[21] clothing, food preparation equipment, or animal and human skin. Petri dishes are widely used in biology to cultivate microorganisms such as bacteria, yeasts, and molds.
