A Petri dish, a mainstay in biology labs, is also known as a Petri plate or a cell-culture dish.
Understanding the Petri Dish
The Petri dish, named after German bacteriologist Julius Richard Petri, is a shallow, transparent, lidded dish used to cultivate cells, including bacteria, fungi, and small mosses. Its simple design allows for easy observation of cellular growth and experimentation. The transparent nature facilitates microscopic examination.
Different materials are used in the manufacturing of Petri dishes. Common materials include glass and plastic. The choice of material depends on the specific application and the required sterilization methods. Some specialized Petri dishes, such as "deep Petri dishes," offer increased volume for cell culture.

Alternative Names: As mentioned, common synonyms for Petri dish include Petri plate and cell-culture dish. These terms are often used interchangeably.
-
Applications: Petri dishes are widely used in microbiology, cell biology, and tissue culture for a variety of purposes, including:
- Growing bacterial colonies
- Culturing cells for research
- Performing microbiological tests
- Observing cellular processes
Why Multiple Names?
The existence of multiple names likely stems from the dish's widespread use and evolution in scientific fields. "Cell-culture dish" emphasizes the functional aspect, while "Petri plate" is simply a slight variation of the original name.
