Question 1 Report
Fig. 3.1 shows a single animal cell that was taken from the moist lining on the inside of a mammal's cheek. Cells of this kind are easy to collect gently and are often used as an example of a typical animal cell when studying cell structure. Before being examined under a light microscope, the cell was treated with a stain, which colours certain parts so that they stand out clearly and can be told apart from one another. The cell has a rounded, irregular outline and does not keep a fixed shape. Four of its parts have been labelled with the letters A to D. Some of these parts are found in the cells of both plants and animals, while a plant cell of the same size would also contain one or two extra structures that this animal cell does not have.
