Prokaryotic cells are simpler than eukaryotic cells for a few reasons:

1. Size and Structure:

   • Prokaryotic cells are usually smaller. They range in size from about 0.1 to 5 micrometers.
   • They don’t have membrane-bound organelles, which means everything is more compact.

2. Nucleus:

   • Prokaryotes don't have a true nucleus. Instead, their DNA is found in a part called the nucleoid, which is not covered by a membrane.
   • Eukaryotic cells have a clear nucleus where their DNA is stored.

3. Reproduction:

   • Prokaryotes often reproduce asexually using a method called binary fission. This is a simpler and faster way than the more complicated processes called mitosis and meiosis that happen in eukaryotes.

4. Cell Wall Composition:

   • Most prokaryotes have a tough cell wall made of peptidoglycan.
   • Eukaryotes can have different kinds of cell walls, like cellulose in plants.

Overall, these features make prokaryotic cells less complex. But they are really good at surviving and reproducing in many different environments!
