At the end of today’s lesson, you should be able to answer the following questions:
-What is the main difference between a prokaryotic and eukaryotic cell?
-What are the parts of a nucleus and where are they located?
-What types of organisms have prokaryotic and eukaryotic cells?
-What are the parts of a prokaryotic cell and what are their functions?
1. The main difference between a prokaryotic cell and eukaryotic cell is…
______________________ contain a ________________________
______________________ DO NOT contain a _________________________
2. Breaking the words down:
-Eukaryotic = ___________ _____________
-Prokaryotic = _______________ ______________
