Angiosperms and Gymnosperms

Angiosperms are flowering plants. Angiosperms are the biggest group in the plant kingdom. They have true roots, stems, leaves and flowers. They also have seeds. The seeds are formed when an egg is fertilized by pollen in the ovary. The ovary is within the flower. The flower contains the male or female parts of the plant. Fruits are frequently produced from these ripened ovaries. Angiosperms are more highly evolved that the algae, mosses, fungi and

They provide lumber for buildings and other objects, fibers for clothes, are the basis for many drugs. Their advanced structures allow them to live on land. Other groups within the gymnosperms include the gingkos and cycads. They are not like the angiosperms that have seeds contained flowers. Gymnosperms are found throughout the world. As the cone grows up, it gets bigger and the seeds that are created by the male pollen and female parts are seen. Angiosperms are the primary food source for animals and provide oxygen for us to breathe. They have leaves that are the major food makers for the plant. Many of these plants are cone-bearing plants. They have stems that hold the plants up and move the nutrients and water about the plant. They have roots that hold the plant in place and take in needed minerals and water. When the needles fall off, they are quickly replaced.
