Flowering plants include not just flowers, but many trees – like this apple tree below. They are all in a group of plants called Angiosperms. Angiosperms carry their seeds protected inside a fruit. Think of how an apple, plum, cherry, grape or peach protects their seeds inside their fleshy bodies.
When an apple tree, or any flowering plant, opens its flowers, pollen from the male part of the plant, called the stamen is moved my insects, birds or the wind to a female flower part called the pistil. The eggs inside the pistil are fertilized by the sperm inside the pollen. Seeds form inside a fleshy fruit. When the fruit drops to the ground, the seeds can sprout right there or be moved to another place by animals that eat the fruit. A new flowering plant will begin to grow.
The cycle begins over again!
