In multicellular organisms, tissue growth rarely occurs solely through cell growth without cell division, but most often occurs through cell proliferation. This is because a single cell with only one copy of the genome in the cell nucleus can perform biosynthesis and thus undergo cell growth at only half the rate of … See more Hey, if you're here, say hi to Nick Gurr for me, alright? refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume.
