Thank you for the opportunity to help you with your question!
The shape of Prokaryotic cells is thaloid. meaning small diameter through them as opposed to the eukaryotic cells block like shape. This clear difference between the two cell makes it possible to compare the Prokaryotic cells with a baseball pitch while comparing eukaryotic's with a building.......the prokaryotic cells are also unicellular, meaning only a single layer thick as compared to the eukaryotic cells multi-cellular structure, giving the later a block like structure due to many underlying cells blocks.
Please let me know if you need any clarification. I'm always happy to answer your questions.
