Subject: How are the shapes of various cell types related to their function?

I am asking in order to do an extra credit assignment for my Biology 
class. I've learned about the general types of eukaryotic, prokaryotic, 
plant, and animal cells. I understand that there are millions of various 
types of cells in order carry out the numerous funtions of certain 
organisms, but I am more interested how the specific shape of the cell is 
related to its function. For example certain types of ceels allow them to 
fitinto small areas.
