Flowering plants shows sexual mode of reproduction and bears complex reproductive units as male and female reproductive units along with accessary structures Flower is a modified stem which functions as a reproductive organ and produces ova and/or pollen A typical angiospermic flower consists of four whorls of floral appendages attached on Flowering plants, also called angiosperms, use a sexual mode of reproduction Reproduction in plants, mainly revolves around the flower, which has both the male and the female gametes All parts of a flower aid in the process of reproduction, although some of them are sterile Therefore, to understand the process of reproduction in flowering plants, we need to look at the different parts of the flowerSexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit
Reproduction 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)The flowers which contain either only the pistil or only the stamens are called unisexual flowersThe flowers which contain both stamens and pistil are called bisexual flowersFlowering involves a change in gene expression in the shoot apex The switch to flowering is a response to the length of light and dark periods in many plants Success in plant reproduction depends on pollination, fertilization and seed dispersal Most flowering plants use mutualistic relationships with pollinators in sexual reproduction
Sexual Reproduction in Plants – Unisexual and Bisexual The flowers are the reproductive parts of a plant The stamens are the male reproductive part and the pistil is the female reproductive part;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 conifersSexual reproduction is the type of reproduction that involves two different parents that belong to the opposite sex This type of reproduction is seen in both plants and animals In plants, sexual reproduction occurs in flowering plants Before we learn more about sexual reproduction in flowering plants, we must understand the anatomy of a flower

Plants also have male and female sex organs These sex organs in plants are carried within the flower and the seeds which are inside a fruit Such plants are called angiosperms or flowering plantsSexual reproduction occurs when two plant sex cells come together to make a seed, which subsequently grows into a new plant Unlike the offspring of asexual reproduction, new plants produced by sexual reproduction are not identical to their parents (Tomlins, 03;1 FLOWERING PLANT REPRODUCTION Abbreviation pr Sections 102 and 301 I BASIC PLANT LIFE CYCLE (section 102, pages 09) Figures 106b shows the life cycle that all plants have The primary difference between this one and the animal life cycle is what happens after meiosis In animals the haploid cells resulting from meiosis become gametes, but in plants they become

Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction Flowering plants are capable of reproducing by both sexual and asexual means Unlike other plants, flowering plants have visible sexual organs called flowers, which facilitate the production and dispersal of seeds and pollen Reproduction in flowering plants begins with the process of pollination during which the male gametes are transferred toPhotosynthesis in Higher Plants Respiration in Plants Plant Growth and Development Reproduction in Organisms Sexual Reproduction in Flowering Plants Principles of Inheritance & Variation Molecular Basis of Inheritance Strategies for Enhancement in Food Production Microbes in Human Welfare
