Angiosperms

Angiosperms are flowering plants that produce seeds enclosed within a fruit. They are the most diverse group of land plants, with over 300,000 species. Angiosperms play a crucial role in the ecosystem, providing food, shelter, and oxygen for many organisms, including humans.

Characteristics of Angiosperms:

• Flowering plants
• Produce seeds enclosed in a fruit
• Have specialized reproductive structures, such as flowers
• Most have broad leaves
• Most have a complex vascular system for transporting water and nutrients

Life Cycle of Angiosperms:

The life cycle of angiosperms includes the following stages:

1. Seed germination
2. Growth of roots, stems, and leaves
3. Formation of flowers
4. Fertilization
5. Seed formation
6. Seed dispersal

Importance of Angiosperms:

Angiosperms are important for several reasons:

• Food production: Many crops, such as wheat, rice, and fruits, are angiosperms.
• Medicinal uses: Many medicines are derived from angiosperms.
• Ecological importance: Angiosperms provide habitats and food for many animals and contribute to the oxygen cycle.
• Aesthetic value: Flowers and ornamental plants enhance the beauty of the environment.
