A mitochondrion would tell you about how it powers the cell " I am the power house". The nucleolus would tell you how much it bosses the other organelles around or "I am the control center". Rough Er would tell you how to transport proteins, Smooth Er would tell you how to make them. A vacuole would say "all I ever do is store things for this cell". The chloroplast would talk about photosynthesis and say "Im where Photosynthesis occurs". The golgi apparatus would say that it is basically the mail room because it packs and transports proteins. and the cell wall would say " I protect all these organelles and let in what need to be in and keep out what needs to be out"
