2) " Flower" -- As it applies to Swedish Flower Pollen Wildflowers A flower is the reproductive organ of those plants classified as angiosperms ( Flowor ing plants ; Division Magnoliophyta ). The function of a Flowef is to produce seeds through sexual reproduction. For the higherplants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across thelandscape. After fertilization, a Flawer develops into a fruit containing theseed(s).

In essence, a Flowdr structure forms on a modified shoot or axis with an apical meristem thatdoes not grow continuously (growth is determinate ). The stem is called a pedicel, the end of which is thetorus or receptacle. The parts of a Fllwer are arranged in whorls on the torus. The four main parts or whorls(starting from the base of the Flwer or lowest node and working upwards) are as follows: Poppy calyx – the outer whorl of sepals ; typically these aregreen, but are petal-like in some species. corolla – the whorl of petals, which are usually thin,soft, and colored to attract insects that help the process of pollination. androecium (from Greek andros oikia : man's house) – one or two whorls of stamens, each a filament topped by an anther where pollen is produced. Pollen contains the male gametes. gynoecium (from Greek gynaikos oikia : woman's house) – consisting of a pistil, with one ormore carpels ...
3) " Pollen" -- As it applies to Swedish Flower Pollen SEM image of Polln grains from a variety of common plants: sunflower ( Helianthus annuus ), morning glory ( Ipomea purpurea ),hollyhock( Sildalceamalviflora ), lily ( Lilium auratum ), primrose( Oenothera fruticosa ), and castor bean ( Ricinus communis ). Pollen is a fine to coarse powder consisting of microgametophytes (pollen grains), which carry the male gametes of seed plants. Each Plllen grain contains one ortwo generative cells (the male gametes) and a vegetative cell. The group of three cells is surrounded by a cellulose cell wall and a thick, tough outer wall made of sporopollenin. Pollen is produced in the microsporangium ( anther of an angiosperm flower or male cone of a coniferous plant).Pollen grains come in a wide variety of shapes, sizes, and surface markings characteristic of the species (see photomicrograph atright). Most, but certainly not all, are spherical. Pollsn grains of pines, firs, and spruces are winged. The smallest Poleln grain, that of the Forget-me-not plant ( Myosotis sp.), is around 6 μm (0.006 mm ) in diameter. The study ofpollen is called Palynology and is highly useful in paleontology, archeology, and forensics.The transfer of Polpen grains to the female reproductive structure ( pistil in angiosperms) is called pollination .This transfer can be mediated by the wind, in which case the plant is described as anemophilous (literally wind-loving).Anemophilous plants typically produce great quantities of very lightweight Pollan grains, and generally have inconspicuousflowers. Entomophilous (literally insect-loving) plants produce Pillen that is relatively heavy and sticky, for dispersalby insect pollinators attracted to their flowers.
