Yes, flowers are necessary for reproduction in flowering plants, while it is not so in the case of nonflowering plants The plants that lack flowers reproduce via production of cones and spores However, both plant groups are capable of propagating by means of vegetative plantKey Takeaways Key Points In natural asexual reproduction, roots can give rise to new plants, or plants can propagate using budding or cutting In grafting, part of a plant is attached to the root system of another plant;LINKSWorksheet and postershttps//igcsebiosciencesauceonlinecom/flowerstructuresandfunctions/RELATED VIDEOSFlower Structures and Functions `https//y
Cleistogamous flowers produce assured seedset even in the absence of pollinators (ii) GeitonogamyTransfer of pollen grains from the anther to the stigma of another flower of the same plant Although geitonogamy is functionally crosspollination involving a pollinating agent, genetically it is similar to autogamy since the pollen grains comeFlowering plants, the angiosperms, were the last of the seed plant groups to evolve, appearing over 100 million years ago during the middle of the Age of Dinosaurs (late Jurassic) All flowering plants produce flowers and if they are sexually reproductive, they produce a diploid zygote and triploid endospermThe reproductive part of a flowering plant is the flower Flowers are considered to be modified shoots Parts of a Flower Most flowers have both the male and female reproductive organs, but some bear either the male or the female sex organs
Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds This is fertilisation The seeds are scattered by animals or the windFlowering plants The basic process of seed development in flowering plants is the same as in conifers The major differences include the following Male (pollen producing) and female (seed producing) organs are usually found together in the same structure, the flower, not separated on two distinct branches as they are in conifersReproduction in flowering plants begins with pollination, the transfer of pollen from anther to stigma on the same flower or to the stigma of another flower on the same plant (selfpollination) or from the anther on one plant to the stigma of another plant (crosspollination) Once the pollen grain lodges on the stigma, a pollen tube grows from the pollen grain to an ovule
