13. One of the functions of a petal in a flowering plant is to a. protect the internal parts of the flower C. support the anther d. make pollen grains b. connect the stigma to the ovary

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.
