The size, structure, and activity of cells vary widely. Mycoplasmas, the tiniest cells, are just 0.3 µm long, whereas bacteria may be 3 to 5 µm long. The egg of an ostrich is the biggest isolated single cell. Nerve cells are among the longest cells in the body. Therefore, the correct answer is option 2.
