In eukaryotic cells up to 10 million present. cryotherapy springfield mo

"WebbInterestingly, the size of ribosomes is not measured by mass. Instead, scientists denote ribosome size by the Svedberg unit (S), which measures the sedimentation rate or the rate at which a molecule moves through a fluid medium. A prokaryotic ribosome typically weighs up to 70S while an Eukaryotic ribosome can weigh about 80S. " - Size of eukaryotic ribosome
