Final answer:
To make up a length of 1000μm with eukaryotic cells having an average diameter of 55μm, you would need about 18 cells, which means at least 19 cells to ensure the total length exceeds 1000μm.
Step-by-step explanation:
To calculate how many eukaryotic cells you need to arrange side by side to make up 1000μm, you need to know the diameter of a typical eukaryotic cell. Eukaryotic cells have diameters ranging from 10 to 100 μm. If we take the average diameter of a eukaryotic cell to be 55 μm (the midpoint of the range), we can determine how many cells you would need by dividing 1000 μm by 55 μm.
1000 μm / 55 μm ≈ 18.18 Therefore, you would need approximately 18 eukaryotic cells to reach a length of 1000 μm when placed side by side. Since you can't have a fraction of a cell, you would need at least 19 cells to ensure the total length reaches or exceeds 1000 μm.
