Anisogamete
Definition
A gamete that is unequal in size, shape, structure, or behavior compared to the opposite sex cell, involved in the sexual reproduction process known as anisogamy. Within differentiated biological systems, it manifests either as a small, highly mobile male microgamete typically powered by flagella, or as a large female macrogamete rich in nutrient reserves intended to sustain the initial development of the zygote.
