Prokaryotic cells differ from eukaryotic cells in that they lack a well-defined nucleus, while eukaryotic cells have a nucleus enclosed by a membrane. Additionally, prokaryotic cells generally have membrane-bound organelles (Query 1) organelles, whereas eukaryotic cells contain various types of membrane-bound organelles (Query 2).
Here’s how the queries can be filled:
- Query 1: few or no
- Query 2: many different types of
So the complete sentences would be: "Prokaryotic cells generally have few or no organelles, whereas eukaryotic cells contain many different types of organelles."
