Angiosperms are flowering plants that produce seeds within a protective ovary structure, which can develop into fruits after fertilization. They are the largest group of plants and play a significant role in the ecosystems as food sources for animals and humans, as well as for their ecological functions.
First, pollen falls on a flower's stigma. In time, the sperm cell and egg cell join together in the flower's ovule. The zygote develops into the embryo part of the seed.

In Gymnosperms, the seeds do not develop in an ovary - they aren't inside a fruit. Gymnosperm seeds develop either on the surface of scale/leaf-like appendages of cones, or at the end of short stalks. Two examples are conifers and cycads. In Angiosperms (flowering plants), the seeds are contained within some kind of fruit, the ovary.
