how do a plant of male flowers with homogamous head  inflorscence can get to its next generation?
482873
Homogamous capitula contain florets that are either bisexual or unisexual.Discoid capitula are usually homogamous containing only disc florets.They are bisexual and so, both self pollination and cross pollination takes place.

to have a good idea have a look at the article below. hoppe it helps...\n\n\n\nPollination Adaptations\nFlowers need to be pollinated. Pollination is the process of moving the pollen grain from the anther of a stamen to the stigma of a carpel. There are a few flowers that can self-pollinate all on their own, but this limits them to inbreeding. Most species rely upon some kind of pollination vector to accomplish pollination. The vector can be any agent that can move pollen from anther to stigma. \n\nThere is evidence of water and wind as the pollination vector in certain species, but many species do not depend upon the random or downstream-only pollination pathways offered by these vectors. Indeed such vectors are only useful in situations where large populations of a very limited number of species are present. \n\nMost flowers have evolved to use a "smart bomb" or "magic bullet" vector...animals! These vectors have sensory organs to locate flowers, they have locomotion to get them to the flowers in spite of large spaces between individuals, and they have enough intelligence to remember that they can depend upon a reward if they visit one particular species repeatedly. \n\nAttracting the Pollinator\nIn order to effectively use an animal pollination vector, a flower needs to attract the animal for the first visit. This can be done in one of two ways: visual cues and olfactory cues. \n\nVisual Cues\nSome species use a color pattern known as a "bull's eye" to mark their position in the environment...to stand out against a background of green foliage. Obviously not too many animal-pollinated flowers are leaf-green! \n\na black-eyed susan...recall that there are over 100 species of unrelated black-eyed susans...one of the problems of common names. This one is in the genus, Rudbeckia. Notice its obvious bull's eye target appearance. The bull's eye is black and the yellow ring surrounds it to make it quite noticeable. \n\n\nThe daylily (Hemerocallis) also shows a prominent bull's eye, but notice how the color pattern is reversed. The bull's eye is light in color and the ring around it is very dark. The effect is the same however, the flower is going to be obvious to a potential pollinator flying overhead. \n\n\nIt is important that whatever color pattern is used is within the visible range of colors observable by the pollinator. Colors obvious to one animal may be invisible to another. Gaillardia (painted daisy). This species obviously uses a yellow bull's eye with surrounding red and yellow rings. One gets the appearance of a dartboard just looking at it. The pollinator visiting is butterflies. Butterflies definitely are attracted to red/yellow patterns, and they need the large landing platform provided by this wide flower. \n\n\nOn the other hand, Gaillardia does not limit its pollination to just butterflies. An afternoon of observation will tell you that even more visits are made by honeybees! Bees have no ability to perceive red colors, so how does that red/yellow pattern look to a bee? This requires some mental translation and some special photography for a human to appreciate what a bee might observe. \n\nFirst we need to eliminate red from the image. This can only be accomplished with fancy video work or black-and-white photography.\n\n\nBee vision does not include red, but it does extend into the ultraviolet. In other words, bees see colors that are invisible to us! Our film is not very sensitive to ultraviolet because it has been developed for showing images visible to humans. To correct that and see the ultraviolet patterns in these flowers, we need to use yet another filter. This filter blocks visible light and allows ultraviolet light to expose the film. Below is the ultraviolet image of the same two daisies taken seconds later with both filters in place: \n\n\ncenter of each daisy is totally absorbing the UV light. The petals around the perimeter are reflecting the UV

Angiosperm Life Cycle\nI. Plant Life Cycles\n\nA. All of us are probably most familiar with the human life cycle. We know that, as adults, most of our cells have two sets of chromosomes, one from our mother and the other from our father. These cells (really the chromosome complement of their nuclei) are called diploid (2N). Special cells undergo meiosis where the chromosome number of the resulting cells are half that of the parent cell. These cells are haploid (1N) and develop directly into gametes (sperm and egg). These gametes fuse during fertilization to produce a zygote which divides through mitosis to form the adult organism. Bear in mind, the two important events in any life cycle (animal or plant) are fertilization and meiosis.\n\nB. In plants, things are a bit different because the products of meiosis (spores) don't immediately become gametes. They divide mitotically to form a completely separate organism! This organism is called the gametophyte and is haploid. The gametophyte may be composed of many cells and be a fully functional plant (such as the green leafy moss) or be composed of only a few cells (as in flowering plants).\n\nC. So how are the gametes formed? The gametophyte produces special structures that make the gametes via mitosis. After fertilization occurs, a diploid zygote forms and grows via mitosis to form the sporophyte which is diploid. This life cycle is called alternation of generations {0256}{0257}{0517}, because the gametophytic and sporophytic stages alternate with each other.\n\nII. Angiosperm Life Cycle {1075}\n\nA. Production of the male gametophyte {0258}. Each anther contains from one to four microsporangia. A microsporangium contains microspore mother cells (microsporocytes) that undergo meiosis producing haploid microspores {0291}{0294}{0295}. Each of the four components of the tetrad {0296} differentiate into pollen grains {0289}. Mitotic divisions result in a mature microgametophyte, otherwise known as pollen. Each pollen grain contains a tube nucleus and a generative nucleus {0290}. When the pollen grain lands on the stigma (below), the generative nucleus divides to form two sperm nuclei. {1086}\n\nB. Production of the female gametophyte {0259}. Inside the ovary are the ovules {0511} that eventually become seeds. The megaspore and later the megagametophyte form inside the ovule. The megagametophyte eventually produces the egg, the female gamete.\n\nInside a young ovule, one cell differentiates into a megaspore mother cell (megasporocyte) {0562}. Meiosis produces four megaspores, but usually only one of these survives. It divides mitotically three times {0563}{0565} giving eight nuclei (in seven cells) {0568}. One cell at the micropyle end of the ovule becomes the egg and the two nuclei in the large central cell function as polar nuclei.\n\nC. Pollination {0260}{0518}{1086}. If the pollen grain is on a compatible stigma, it attaches, germinates and forms a pollen tube which grows through the style tissue on its way to the ovule.\n\nD. Fertilization. When the pollen tube reaches the micropyle opening, it releases two sperm nuclei. One fuses with the egg forming a zygote {0261}, the other fuses with the already fused polar nuclei making a triploid fusion nucleus. This DOUBLE FERTILIZATION is a feature found only in angiosperms. The triploid fusion nucleus divides mitotically to form endosperm which is used as a nutritive tissue for the growing embryo {0615}.\n\nD. Fruits and seeds {0538}. The mature ovule becomes the seed. The integuments become the seed coat that surrounds the endosperm and embryo. The mature carpel (and sometimes associated tissues) becomes the fruit.

In angiosperms, the sporophyte (2n) stage predominates and includes the\nvegetative parts of the plant and even the various parts of the flower. The process involving meiosis, which converts\ndiploid sporocytes (or spore mother cells) into haploid (n) spores, is termed sporogenesis. Sporogenesis occurs in the\nanthers of stamens and the ovules of pistils. Angiosperms, and seed plants in general, are heterosporous. This means\nthat two different kinds of spores, microspore and megaspore, are produced by the sporophyte. Consequently,\nheterosporous organisms exhibit separate male and female gametophytes. The microspore gives rise to the\nmicrogametophyte (or male gametophyte), and the megaspore gives rise to the megagametophyte (or female\ngametophyte).

yes, each pistil can be fertilized by different pollen, but generally the properties of the fruit is dependant on the genes of the mother - the flesh of the fruit is mother tissue, so the dna of the seed is not affecting this much. that is why all the apples, cherries on one tree are quite the same even it they were pollinated by different "fathers" - but if u grow the seeds in mature trees, they may differ in their various properties.

Sexual reproduction-Sexual dispersal in Equisetum occurs by means of spores.  Equisetum spores are green, spherical, and have thin spore walls.  Each Equisetum spore has four unique strap-like structures called elaters attached to the spore surface at a common point.  These elaters are hygroscopic (i.e. they expand and contract with changes in humidity) and probably function to help disperse the spores.Equisetum spores are short-lived and can germinate within 24 hours of release from the cone.  After 5-17 days, depending on humidity, they are no longer capable of germination .In nontropical species (the majority of Equisetum ), the spores are produced over a short period of time during the growing season .Equisetum gametophytes appear to require a substrate of recently exposed bare mud in order to become established .Like pioneer species, they rapidly attain sexual maturity and are adversely affected by competition from bryophytes and vascular plants .The resulting inefficiency of spore germination and gametophyte reproduction in non-pioneer situations probably limits gene flow and leads the high degree of genetic divergence found between Equisetum populations. Therefore, sexual reproduction in Equisetum is limited to rather narrow ecological conditions and this limits the dispersal ability of Equisetum via spores.\n\nAsexual Reoroduction-Equisetum species have a remarkable ability to reproduce vegetatively.  This helps to compensate for the inefficiency of spore reproduction.  An extensive rhizome system allows Equisetum species to rapidly colonize disturbed areas .This ability gives Equisetum a distinct advantage over species requiring seed establishment or which have slow-growing rhizomes .For instance, the widespread creation of roadside ditches in America has created significant new habitat for some Equisetum species.  This is because the soil in ditch habitats tends to be moist and the rhizomatous growth of Equisetum species allows them to survive and thrive under the conditions of sediment accumulation that are characteristic of ditches .The ability of Equisetum to survive and spread in areas of heavy sediment accumulation was dramatically demonstrated after the 1912 eruption of Katmai Volcano in Alaska.  In studies of vegetational recovery from the volcanic tephra (ash and silt) deposited by this eruption, E. arvense was found to be the most successful herb.  It was able to penetrate as much as one meter of tephra, more than any other herbaceous species, and colonize large areas via rapid rhizomatous growth The remarkable ability of Equisetum to prosper under disturbed conditions was also demonstrated after the eruption of Mount St. Helens in 1980 when Equisetum formed almost monotypic stands in the newly deposited tephra .The deep rhizome system of Equisetum also allows these plants to survive fire and rapidly recolonize burned-over sites .It is probable that the vigorous and extensive rhizomatous habit of Equisetum has been very important to the long term survival and spread of the genus .\n\nVegetative reproduction - Fragmentation of rhizomes and stems allows Equisetum to disperse readily in suitable habitats where there is sufficient moisture.  Even the aerial stem fragments can sprout and form new colonies .Hence, vegetative reproduction allows Equisetum clones to persist and spread even in the absence of sexual reproduction .\nVegetative reproduction probably accounts for the widespread occurrence and persistence of common Equisetum hybrids even where one or both of the parents are absent .  This is because hybrids are generally sterile and hence are without means of sexual reproduction.  The rhizome system of a vigorous hybrid clone theoretically has the ability to maintain dense colonies within limited areas for long periods.  Fragmentation and transport of rhizomes and stems then has the potential to disperse the clone from the site of the original hybridization .  This would account for the abundance of Equis

You would get two different genotypes and phenotypes.\nIf you were crossing a tall, heterozygous plant, Tt with a short plant, tt, you would get 50% Tt and 50% tt.

Pollen, or flower sperm, is a fine to coarse powder consisting of microgametophytes (pollen grains), which carry the male gametes of seed plants. Each pollen grain contains one or two 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.\nThe transfer of pollen 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 pollen grains, often with air-sacs, and generally have inconspicuous flowers. Entomophilous (literally insect-loving) plants produce pollen that is relatively heavy, sticky and protein-rich, for dispersal by insect pollinators attracted to their flowers.\n\nWhen placed on the stigma, under favorable circumstances, the pollen-grain puts forth a pollen-tube which grows down the tissue of the style to the ovary, and makes its way along the placenta, guided by projections or hairs, to the mouth of an ovule. The nucleus of the tube-cell has meanwhile passed into the tube, as does also the generative nucleus which divides to form two male- or sperm-cells. The male-cells are carried to their destination in the tip of the pollen-tube.\n\nA seed is the ripened ovule of gymnosperm or angiosperm plants. The importance of the seed relative to more primitive forms of reproduction and dispersal is attested to by the success of these two groups of plants in dominating the landscape.

There are many different types of "sex" practiced in the plant and animal kingdoms besides the type we humans are familiar with. There are species in which the fathers get pregnant (like seahorses). There are species where males will turn into females (or vice-versa) if it would help the species survive. There are lots of examples of parthenogensis (virgin birth). There are cases where a single individual (like a plant) will pollinate itself, but others where biology tries to prevent this, although the plant might be hermaphroditic. There are plants which have several different reproduction mechanisms; a piece of the root can produce a new individual, for example. Some organisms can engage in both sexual and asexual reproduction as well; earthworms, honeybees, and geckos can asexually reproduce. There are species with 3 or even more sexes (like the clam shrimp in the US, for example, which has 3 sexes, or possibly  the New Zealand lizard the tuatara, which appears to have 4 sexes. There are species where males just fertilize the eggs deposited by the female in some location (most fish). Bacteria and viruses reproduce in strange ways, by dividing, or by taking over the reproduction mechanism of some other organism. \n\nThe astounding variety of "sex" and/or reproduction just goes on and on and on. We are still learning about the amazing diversity of life on this planet. \n\nIf and when we ever discover life on other planets, you can be sure that they will have different ways to reproduce, that may or may not have anything to do with what we might recognize as sex, and probably using mechanisms we cannot even imagine.
