Flower is a modified shoot because a) in some flowers thalamus become elongated and shows distinct nodes and internodes b) flowers aggregate to form inflorescence.
Flowers initiated the differences between gymnosperms and angiosperms by broadening the scope of evolutionary relationships and niches open to flowering plants, allowing them to eventually . In simple terms, a flower is the reproductive mechanism of an angiosperm most flowers have both male and female parts reproduction begins when a flower releases pollen, microscopic packets of . Angiosperms are far more numerous than gymnosperms angiosperms evolved from gymnosperms and have been around for at least 202 million years their flowers are their reproductive organs.

The term angiosperm is derived from the greek words for vessel and seed, alluding to the fact that their seeds are borne within an ovary, a protective structure within the flower angiosperms represent an advancement over gymnosperms not only in that their seeds are more protected, but also in their modes of pollination. As was true in the gymnosperms, the main plants in angiosperms are sporophytes, while the gametophytes are confined to the flowers, usually male and female together. Flower – with its composition of essential and inessential parts, the flower lures insects, birds, bats to itself, and in the process has dramatically increased the diversity of flowering plants co-evolution (mutual adaptation) with insects. Angiosperms are the biggest group in the plant kingdom they have true roots, stems, leaves and flowers they also have seedsthe seeds are formed when an egg or ovule is fertilized by pollen in the ovary.

The aquatic habit and simple flowers seemed at odds with most hypotheses about the earliest angiosperms, although ceratophyllum has a long fossil record, going back at least 125 mya (dilcher, 1989) subsequent analyses demonstrated that this placement was unique to the rbcl data set. The flower itself, which comprises most of the evolutionary innovations of flowering plants, bears special significance for understanding the origin and diversification of angiosperms the sudden .
Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower the flowers of angiosperms have male or female reproductive organs pollination. Some defining characteristics of angiosperms include flowers, carpels, and the presence of endosperm, a nutritive substance found in seeds, produced via a second fertilization event however, some current studies suggest that endosperm is not unique to angiosperms.
Most flowers have showy petals to attract pollinators, bribing insects and other animals with nectar, to get them to carry the male gametophyte through the air to another flower animal pollination is common in angiosperms, in contrast to the mostly wind-pollinated gymnosperms. Early flowers and angiosperm evolution is a definitive book it is detailed, accessible and offers a synthetic perspective from a team that has been thinking deeply . Angiosperm: angiosperm, any of about 300,000 species of flowering plants, the largest and most diverse group in the plant kingdom angiosperms are vascular seed plants in which the ovule is fertilized and develops into a seed in an enclosed ovary.
