I saw this elsewhere. I'm confused b/c while single-cell organisms exist, a fertilized egg is 2 cells. What am I missing? An unfertilized ovum isn't any more alive than a skin cell, right?
“A zygote (from Greek ζυγωτός zygōtos “joined” or “yoked”, from ζυγοῦν zygoun “to join” or “to yoke”), or zygocyte, is the initial cell formed when two gamete cells are joined by means of sexual reproduction.”

A fertilized egg is a zygote and thus one cell:
“A zygote (from Greek ζυγωτός zygōtos “joined” or “yoked”, from ζυγοῦν zygoun “to join” or “to yoke”), or zygocyte, is the initial cell formed when two gamete cells are joined by means of sexual reproduction.”
