Anther: The anther is part of the stamen and produces the pollen.
Corolla: The whorl of petals is called the corolla.
Filament: The filament provides support for the anther in the stamen.
Ovary: The ovary houses the ovules and will become the fruit after pollination.
Ovule: The ovules contain egg cells and become the seeds after pollination.
Petal: The petal is designed to attract pollinators to the flower and protect the stamen and pistil. Many have patterns that can be seen in ultraviolet light by bees and other insects. These indicate where the nectar is located.
Sepal: Sepals are found on the outside of the flower in a whorl. They are usually green. The group of sepals is called the calyx.
Stamen: The stamen is the male reproductive organ in the plant. It consists of the anther and filament.
Stigma: The stigma is the sticky surface where pollen lands and is collected to fertilize the ovules.
Style: The style is part of the pistil and holds the stigma above the ovary.
Carpel: the innermost whorl of a flower, consisting of one or more units called carpels. The carpel or multiple fused carpels form a hollow structure called an ovary, which produces ovules internally.
