1. The diagrams below show some human cheek cells as they appeared under the microscope, at two different magnifications.<\/span><\/p>\n

<\/a><\/p>\n

Describe the effect that increasing the magnification had on:<\/span><\/p>\n

b) the area of the slide seen.<\/span><\/p>\n

c) why do we use stains when looking at cells under the microscope?<\/span><\/p>\n

2. The diagram opposite shows some human cheek cells as they appear when viewed through a microscope.<\/span><\/p>\n

\"1\"<\/a>
