Hi There!
Tell me a little about prokaryotic and eukaryotes.
What do these types of cells have in common?
How are they different?
2 very common similarities between the types of cells is that they both have a certain type of structure and all cells have a plasma membrane, DNA, ribosome, etc. They are different in a way that eukaryotes have a "membrane-bound organelle" which usualy includes it having a nucleus. Whats cool is that eukaryotes can be multicellular or singled celled> For Example, plants, insects, and fungi. Prokaryotes don't have a nucleus or organelle (membrane bound).
Hope This Helps :)
