20. Activity!
Collect the cell function card sort activity and correctly match the structure with the function!
Once you have finished copy the cell function table into your jotter!

21. Stains
Stains are used to view cells under a microscope so that we can see the cell structures more clearly
To view cheek cells, we use methylene blue
To view onion cells, we use iodine solution
Clearly / iodine solution / methylene blue / Structures

22. Field oF view
The diagram below shows some animal cells under the microscope.
Lets work it out!
Count the cells in the field of view
Divide the ‘field of view’ length by the number of cells.
Remember to add in units!
Field of view = 150 units
Calculate the average diameter of one animal cell.
