Calculate actual size from magnification
A micrograph in a Melbourne HL Biology microscopy seminar shows a cell image length of \(48\) mm at \(\times 600\) magnification. Calculate actual cell length in micrometres. Use the diagram labels, HL model, or quantitative image evidence before answering. Enter the answer and choose the interpretation that best matches the HL biological evidence.
Worked practice: biological evidence and answer
Use the labelled biological evidence first, then connect it to the final answer.
