Diagram of a flower showing the pistil, stigma, style, ovary, stamen, anther, filament, petal, ovule with embryo sac, sepal, receptacle, and peduncle.

Peduncle: The stalk of a flower. 
Receptacle: The part of a flower stalk where the parts of the flower are attached. 
Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud. 
Petal: The parts of a flower that are often conspicuously colored. 
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. 
Anther: The part of the stamen where pollen is produced. 
Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. 
Stigma: The part of the pistil where pollen germinates. 
Ovary: The enlarged basal portion of the pistil where ovules are produced.
