A Petri dish is one of the most iconic tools in microbiology and scientific research. It is a shallow, cylindrical, transparent dish made of glass or plastic, used primarily to culture microorganisms such as bacteria, fungi, and cells. The dish is typically filled with a nutrient-rich agar medium, which provides the necessary environment for microbes to grow. https://www.sinymedical.com/what-is-a-petri-dish/
