Its late and i am tired so i will do my best to come up with some answers but because i am tired i will not look up answers.





Yeast cell is unicellular, mushroom is multicellular.





Yeast is used to make cheese, bread, beer, its been known to degrade tnt and other things, ethanol fuel.





Mould is eaten in cheese, it can make you sick (spores and the like), it can make you better by killing bacteria (penicillin)





because the basic shape is something that changes over the course of the life cycle, not to mention that some basic shapes are decieving.
