Final answer:
You would need 1000 prokaryotic cells placed side by side to make 1000 μm.
Step-by-step explanation:
Prokaryotic cells are typically 0.1 to 5.0 μm in diameter, while eukaryotic cells have diameters ranging from 10 to 100 μm. To calculate how many prokaryotic cells can fit side by side to make 1000 μm, we need to find the average size of a prokaryotic cell. Let's assume a size of 1 μm for simplicity. Dividing 1000 μm by 1 μm, we find that you would need 1000 prokaryotic cells placed side by side to make 1000 μm.
