WebbThe 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 … Webb14 maj 2024 · Shape, size and function Ribosomes are roughly spherical with a diameter of ~20 nm, they can be seen only with the electron microscope.
