Egg cell
Egg Cell
An Egg Cell, also known as an Ovum (plural Ova), is the female reproductive cell or gamete in most anisogamous organisms (organisms that reproduce sexually with a larger, "female" gamete and a smaller, "male" one). The term is used when the female gamete is not capable of movement (non-motile). If the female gamete is capable of movement, it is often referred to as an oocyte.
Pronunciation
- Egg Cell: /ɛɡ sɛl/
- Ovum: /ˈoʊvəm/
Etymology
The term "Egg Cell" is derived from the Old Norse word "egg", which means "bird's egg, ovum, testicle", and the Old English word "cella", meaning "small room". "Ovum" is derived from the Latin word "ovum" which means "egg".
