Types of Flowers
Have you ever eaten an apple or an orange? If you have, you may have seen the seeds inside the core of the apple or the slices of an orange. If you were to plant those seeds, you could grow an apple or orange tree.
Seeds are what plants use to make new plants, and the flower of a plant is what makes those seeds. Flowers can have all male parts, all female parts, or a combination of both. Imperfect flowers are those that have all male or all female parts. Perfect flowers have both male and female parts.

Male Flower Parts
The stamen is the male part of the flower. It's made of the anther and the filament. The filament is the stalk that supports the anther. The anther produces and stores pollen. The pollen carries the cells that are needed to mate with the female parts. The outer layer of the pollen is very strong and keeps the pollen grain from being destroyed. It works so well that pollen grains have been found in fossils from hundreds of years ago!
Female Flower Parts
The pistil is the female part of the flower. It's made up of the ovaries, ovules, stigma, and style. The stigma is the tip of the pistil that receives pollen grains on its sticky surface. The ovary contains the ovules, which combine with pollen to form the seeds of the flower, while the style is the long stalk that connects the stigma to the ovary.
Other Flower Parts
The pistil and the stamen are not the only parts of the flower. The receptacle, sepal, and petal all have important functions, too. The receptacle is the part of the flower to which all of the other parts are attached. It holds the flower together. Before the flower blooms, the sepal covers the closed bud to protect it. When the flower is ready to open, the sepal curls back.
Perfect flowers with all male parts need a way to carry their pollen to the ovule of another flower. The petal is the bright, colorful part of the plant that attracts pollinators like bees, hummingbirds, and flies. When these pollinators land on the anther, they pick up its pollen, and then when they fly away they spread it to other flowers. Pollen can also be spread by the wind, but most of the pollen ends up going to waste. Flowers that use wind pollination usually don't have colorful petals. This is because they don't need to attract pollinators.
Let's review what we learned in this lesson. Plants need flowers to produce seeds that make new plants. Imperfect flowers are those that have all male or all female parts, while perfect flowers have both male and female parts. The stamen is the male part of the flower, which is made up of the anther and the filament. The pistil is the female part of the flower, which is made up of the ovary, ovules, stigma, and style. Other parts of a flower include the receptacle, sepal, and petal. The petal is the bright, colorful part of the plant that attracts pollinators like bees, hummingbirds, and flies.
