They are usually used to culture cells - often bacteria. This may be to obtain a large enough sample to test for diagnostic purposes, to test medicines and so on.
A petri dish is a tool, not a math function. It is a shallow glass or plastic cylindrical lidded dish that biologists use to culture cells.
It is called a petri dish or culture dish, and it is used in microbiology to culture and observe the growth of bacteria, mold, or other microorganisms.

A Petri dish is a small, clear plastic dish that is used in science and experiments.
A petri dish is used in laboratory experiments to hold and grow cultures of microorganisms or cells. It provides a controlled environment for studying the growth and behavior of these organisms under specific conditions.
A Petri dish (or Petri plate or cell culture dish) is a shallow glass or plastic cylindricallidded dish that biologists use to culture cells[1]or small moss plants.[2
This is called a petri dish named after a German bacteriologist, Julius Petri.
A Petri dish is used in scientific research to culture cells, bacteria, or other microorganisms in a controlled environment. It provides a flat, transparent surface for observing growth and interactions between organisms.
Julius Richard Petri is known for being the inventor of the petri dish. In early bacteria studies, cultures were kept in lidless dishes and as a result they often became contaminated. Julius Richard Petri invented a dish with a lid that reduced the risk of contamination and this has become known as the petri dish.
It's called a Petri dish, name after German bacteriologist Julius Richard Petri.
Because during incubation moisture will form at the top of the petri dish. Inverting the dish prevents it from dropping into whatever you have in the petri dish.
