Relating to a type of cell involved in the formation of eggs in certain organisms.
The oogonial cells are essential for the development of female gametes in many species.
Oogonial is derived from "oogonium" (from Greek "oogonion", meaning egg or ovum) and the suffix "-ial" (meaning relating to). The term "oogonial" refers to something that is related to or characteristic of the oogonium, which is the female gametangium in certain algae and fungi.
Think of 'oogonium' which relates to 'egg' in Greek, and remember that 'oogonial' describes something related to eggs or female reproductive structures.
