• Prokaryotic = type of cell; very simple; evolved early; no nucleus
• Eukaryotic = type of cell; complex; evolved later; contains nucleus and other organelles
Eukaryotic cell = more complex; evolved later; Eukaryotic cell = more complex; evolved later; contains a nucleus (and many other contains a nucleus (and many other organelles)organelles)
