Culture Dish Reverse: practical apparatus
What Culture Dish Reverse Is Used For
Culture Dish Reverse 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 reverse to handling cultures during microbiology practical work, rather than only saying that it is used in a lab.

Common Trap
Do not describe apparatus by appearance only. Marks usually come from explaining its function in the practical method.
Ribosome diagram
Recognising Ribosome
Ribosome supports Culturing microorganisms (biology only) by giving students a diagram they can connect to the specification point being tested.
What To Explain
The answer should name the cell structure and link it to its function, such as control, respiration, photosynthesis or protein synthesis.
