Answer 1

Cheek cells are eukaryotic cells (cells that contain a nucleus and other organelles within enclosed in a membrane) that are easily shed from the mouth lining. It is therefore easy to obtain them for observation.

Answer:

If you look at a microscope image of the nucleus, you may notice – depending on the type of stain used to visualize the cell – that there's a dark spot inside it. This darkly staining region is called the nucleolus, and it's the site in which new ribosomes are assembled.
