A class of organisms composed of one or more cells containing a membrane-enclosed nucleus and organelles. This class constitutes one of three distinct evolutionary lineages (eubacteria, eukaryotes & archaea) of modern-day organisms. Includes all organisms except viruses and prokaryotes (mostly bacteria).
Synonyms: eukarya, eukaryotes, eukaryotic organisms
Human eyelashes are sometimes used in worm selection or cultivation as they can be more delicate for handling the worm than a traditional platinum wire pick (dog hair can be used as well). Eyelashes may also be used as a size reference.
