The correct answer is Angiosperm. Explanation & Key Takeaways: • Angiosperms are also known as Angiospermae or Magnoliophyta. • They are flowering and seed-producing plants. • It consists of 64 orders, 416 families, approximately 13,000 known genera, and 3,00,000 known species. • Their seeds develop in the ovaries of flowers and are surrounded by a protective fruit. • Examples of angiosperms are fruits, vegetables, grains, and flowers. • Angiosperms are classified as Monocotyledons (monocots) and Dicotyledons (dicots) where monocots are flowering plants whose seeds contain only one embryonic leaf or cotyledon and dicots are flowering plants whose seeds contain two embryonic leaves or cotyledons. Important Notes: • Naked embryos are formed after fertilization and are not formed inside the seed. • These are also known as spores. • These embryos are the characteristic feature of Bryophytes and Pteridophytes. • The reproductive organs bearing spores are also called sori. • They also occur in various species of marine organisms like algae. Related Concepts: • Thallophyta • The plant body is not differentiated from roots, stems, and leaves. • They are commonly called algae. • Bryophyta • These are small terrestrial plants. • They show differentiation in the body design, with stem, leaf-like structures, and root-like structures. • Pteridophyta • Plants from this group have well-developed roots, stems and leaves and separate tissues for the conduction of food and water. But, they do not bear flowers and fruits. • They reproduce with the help of spores formed along the back or posterior surface of their leaves. • Examples- ferns like Nephrolepis, Marsilea, Pteris, Adiantum, Equisetum, Selaginella, Lycopodium, etc.
