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

Ribosome diagram
Recognising Ribosome
Ribosome supports Microscope Technology and Cellular Understanding 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.

Exam Answer Move
The mapped objective is: Build an explanation of the way changes in microscope technology, covering electron microscopy, have enabled us to see cell structures and organelles with more clarity and detail than in the past and increased our understanding of the role of sub-cellular structures. Diagram marks usually come from linking a named structure to what it does.
