The ovaries are located in the pelvis, one on each side of the uterus. Fertilization typically takes place in this region.analogous structures - structures having similar function or superficial appearance, but not necessarily sharing a common evolutionary origin (contrast with homologous structures). The ovaries are typically found in pairs; however, both are not functional in all animals (e.g., birds and some fish species).

In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Ovary DefinitionAn ovary refers to the female reproductive organ in vertebrates that produces the female gametes (eggs/oocytes) and functions as an exocrine gland. When the ovule (egg cell) within the ~TildeLink() becomes fertilized, it develops into a seed.

"The ~TildeLink(), thus formed from the genital ridge, is at first a mass of cells derived from the celomic epithelium; later the mass is differentiated into a central part or medulla (Fig. The ovaries are typically found in pairs; however, both are not functional in all animals (e.g., birds and some fish species ).

An ovary refers to the female reproductive organ in vertebrates that produces the female gametes (eggs/oocytes) and functions as an exocrine gland. Two major plant divisions are covered: the angiosperms and the gymnosperms. This tutorial elaborates on the physical development of humans, particularly from puberty to adulthood.
