hlo frnds❤❤❤❤❤❤❤❤❤❤❤plz send me life cycle of angiosperm❤❤

Answer 1

The life cycle of an angiosperm is shown. Anthers and carpels are structures that shelter the actual gametophytes the pollen grain and embryo sac. Double fertilization is a process unique to angiosperms.

Answer 2

Angiosperms, or flowering plants, are the most abundant and diverse plants on Earth. Angiosperms evolved several reproductive adaptations that have contributed to their success. Like all vascular plants, their life cycle is dominated by the sporophytegeneration. A typical angiosperm life cycle is shown in above Figure .


The flower in Figure above is obviously an innovation in the angiosperm life cycle.Flowers form on the dominant sporophyteplant. They consist of highly specialized male and female reproductive organs. Flowers produce spores that develop intogametophytes. Male gametophytes consist of just a few cells within a pollen grain and produce sperm. Female gametophytes produce eggs inside the ovaries of flowers. Flowers also attract animal pollinators.

If pollination and fertilization occur, a diploid zygote forms within an ovule in the ovary. The zygote develops into an embryo inside a seed, which forms from the ovule and also contains food to nourish the embryo. The ovary surrounding the seed may develop into a fruit. Fruits attract animals that may disperse the seeds they contain. If a seed germinates, it may grow into a mature sporophyte plant and repeat the cycle.
