Why Are Cells The Size They Are? Gravity May Be A Factor
Eukaryotic cells, which are defined by having a nucleus, rarely grow larger than 10 μm in diameter. Scientists know a few reasons why this is so. For example, cells with a larger volume have a harder time obtaining nutrients from their surroundings. A new study suggests another reason—gravity (Nat. Cell Biol. 2013, DOI: 10.1038/ncb2830).
Scientists had thought gravity’s effects at the cellular . . .
