The average size of a human cell varies quite a lot. a single nerve cell can be up to a meter long while a cheek cell averages about 50 micrometers or .05 mm. the average cell though is between 10 micrometers and 100 micrometers.
Cells can vary between 1 micrometer (Î¼m) and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 Î¼m).ll known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a eukaryote. Some eukaryotes, like amoebae, are free-living, single-celled entities.
