    What Culture Dish Is Used For

    Culture Dish is practical apparatus for handling cultures during microbiology practical work. In GCSE or introductory practical science, the annotated diagram helps connect the apparatus to the method, measurement, or observation being tested.

    How To Use It In An Exam Answer

    Use the marker labels to name the apparatus first, then say why it is suitable. A strong answer links culture dish to handling cultures during microbiology practical work, rather than only saying that it is used in a lab.
