Hi!
What about using your brains? Didn`t you see any difference between the
three objects?
Your teacher made you draw in order to make you look at the objekts
intensely. You have to look again many times more as when you simply
watch the cells and then discard them.
So, as you obviously have not looked often enough you should either
repeat the experiment or get a book with descent pictures/photographs of
the desired cells under a microscope. A textbook might also be helpfull
to detect the differences between animal cells, photosynthetik active
cells of an aquatic plant and cells of an organ that serves to get a
plant over the dark and cold period of the year...
