An egg cell is the female reproductive cell that contains half the genetic information needed to create a new organism. It matters because when an egg cell combines with a sperm cell during fertilization, the two halves come together to form a complete genetic blueprint for a developing baby.

Die Eizelle, kurz Ei (lateinisch Ovum, Mehrzahl: ova), oder Oocyte (oder Oozyte, von altgriechisch ᾠόν ōón „Ei“ und κύτος kytos „Hülle, Haut“; die Vokale zu Beginn sind getrennt auszusprechen: „O-o-zy-te“) ist die weibliche Keimzelle zweigeschlechtlicher Lebewesen. Sie dient der generativen Vermehrung durch Oogamie und enthält alle genetischen Anlagen des weiblichen Lebewesens, die an den Nachkommen weitergegeben werden. Eizellen sind haploide Zellen, enthalten also nur einen Chromosomensatz. Während der männliche Gamet, z. B. das Spermium, lediglich Kern-DNA bei der Bildung der Zygote beisteuert, liefert die Eizelle in der Regel die allgemeine zelluläre Umgebung wie das Cytoplasma und die in ihm vorhandenen Organellen. Mitochondrien und Plastiden (bei Pflanzen) enthalten ebenfalls DNA, die meist rein maternal (mütterlicherseits) vererbt wird.
