Why do some fruits grow in 'slices'?

For example, the clementine or the orange, they come in slices that each have a sort of skin separating them from other slices. Why do these and many other fruits grow like this?

Fruits develop from the female part of a flower called an ovary (like the ovary in animals, but only by analogy). Each ovary contains one or more smaller structures inside it called ovules that will develop into the seeds, while the ovary itself becomes the fruit. A lot of fruits are actually made from several ovaries fused together and even when they're mature fruits you can still see the separate ovaries. This includes the citrus fruits you mentioned where each section matures from a separate ovary. You can also see separate ovaries in apples, tomatoes, melons, cucumbers, bananas, and lots of other fruits if you cut them the right way, though they're not quite as distinct as in citrus fruits.
