WebThe size of Earth-bound bacteria is dictated by a number of factors, the most important of which is the growth rate. If we postulate that ancient cells had very slow growth rates and therefore required few ribosomes, and if they lived in nutritionally rich surroundings, thus requiring few biosynthetic enzymes, they could conceivably be as small as a 200 … WebMar 17, 2024 · Cell diameter: 30 micrometers* 300 feet: Nucleus diameter: 5 micrometers: 50 feet: Mitochondrion length: Typically 1-2 micrometers but can be up to 7 micrometers long: 18 feet: Lysosome diameter: 50-3,000 nanometers* 5 inches to 30 feet: Ribosome diameter: 20-30 nanometers: 2-3 inches *A micrometer is 1 millionth of a meter.
