Mitosis and MeiosisThey sound alike, sort of
look alike, the stages have the same name but
these are two unique cell processes with
completely different outcomes. Take a few
moments to consider how mitosis and meiosis are
different and describe those differences. Also
consider ways a process like meiosis is so
necessary in cells and explain this as well. Use
the proper vocabulary and complete sentences.
Even drawings if they help. Use your notes of
course!
