ANGIOSPERMS are a diverse group of plants which protect their seeds within an ovary called as fruit. These are flowering plants.They evolved during Late CRETACEOUS period about 125 million yeras ago. We can say angiosperms as SEED IN A VESSEL. 1.Based on megascopic or palyonological remains, the diversification of flowering plants initial appaerance differ. 2.About 90 million years ago, there is a widespread dominance in megafloral assemblage of northern hemisphere. 3. Based on palyonological data, Angiosperm dominance occured during Turonian period due to opening of ecological niche which provided an oppurtunity to angiosperms to diversify. PATTERNS OF DIVERSIFICATION a) Angiosperms appear in low number and confined to stream margin habitats in Barremian. During this angiosperms also called as PALEOHERBS. b) Flowering plants during MID-ALBIAN are dominant. c) During LATE ALBIAN-MIDDLE CINNOMANIAN, major foliage types are found d) During CENOMANIAN to CONIACIAN there is a increased diversity of angiosperms. Angiosperms produce gametes in seperate organs which are usually housed ina flower. Both Fertilizaton and embryo develipment takes place inside the anatomical structure. These are diverse phylum on earth after insects. Flowers come in different sizes,shapes, colors and smells. Most flowers have mutualistic pollinator and flower different charactersitics of flowers reflecting nature of pollination agent. The relation between pollinator and flower features is an example for COEVOLUTION. Solution ANGIOSPERMS are a diverse group of plants which protect their seeds within an ovary called as fruit.
