Biology - How large are cells?

How large are cells?

The size of cells varies within the same organism [1] and between
organisms.

The human cheek cell and leaf cells have lengths of 56mm and 90mm
respectively. Plant cells tend to be larger than animal cells.

Now that you have read the information on magnification and cell sizes you
should be able to:
1. define 'magnification',
2. explain how to calculate magnification,
3. determine the field of view for a particular magnification,
4. determine the size of a magnified object and
5. explain in simple terms whether there are differences in cell sizes
within an organism and between organisms.
