Asexual reproduction\n\n\nAsexual reproduction is the biological process by which an organism creates a genetically-similar or identical copy of itself without a contribution of genetic material from another individual. Bacteria divide asexually via binary fission; viruses take control of host cells to produce more viruses; Hydras (invertebrates of the order Hydroidea) and yeasts are able to reproduce by budding. These organisms do not have different sexes, and they are capable of "splitting" themselves into two or more individuals. Some 'asexual' species, like hydra and jellyfish, may also reproduce sexually. For instance, most plants are capable of vegetative reproduction—reproduction without seeds or spores—but can as well reproduce sexually. Likewise, bacteria may exchange genetic information by conjugation. Other ways of asexual reproduction include fragmentation and spore formation that involves only mitosis.\n\n\nSexual reproduction\n\nSexual reproduction is a biological process by which organisms create descendants that have a combination of genetic material contributed from two (usually) different members of the species. Each of two parent organisms contributes half of the offspring's genetic makeup by creating haploid gametes. Most organisms form two different types of gametes. In these anisogamous species, the two sexes are referred to as male (producing sperm or microspores) and female (producing ova or megaspores). In isogamous species the gametes are similar or identical in form, but may have separable properties and then may be given other different names. For example, in the green alga, Chlamydomonas reinhardtii, there are so-called "plus" and "minus" gametes. A few types of organisms, such as ciliates, have more than two kinds of gametes.\n\nHumans, most animals, and plants reproduce sexually. Sexually-reproducing organisms have two sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each parent, thereby ensuring that offspring have a combination of the parents' genes. Having two copies of every gene, only one of which is expressed, allows deleterious alleles to be masked, an advantage believed to have led to the evolutionary development of diploidy (Otto and Goldstein).

I recall looking into the importance of flowers in art nouveau when I was in college and not finding a whole lot of material (a chapter here or there.)  I suggest using the library at a large college, preferably a liberal arts college.  I have only one book on art nouveau, Art Nouveau, Spirit of the Belle Epoque. by Susan A. Sternau.  It comments on some of the motifs common to art nouveau, but never really goes into any great detail.  It is more of a summary on the art style with some pretty sharp color pictures.

Hi Erica, \n\nI'd waste both your and my time if I try to answer this question with lots of detail. I'd suggest you go to your textbook, flip a few pages here and there, get a broad idea and then, come back and read this answer. \n\nPlease notice that I'll have to make this answer less complex by generalizing concepts and avoiding some fine details which you can easily read in your textbook.\n\nNow, without wasting much time, here is my answer-\n\n===================\n\nCharacteristics of animal sexual life cycles-\n\n1- Usually, there are two parents- male and female. Both form special haploid cells called gametes by meiosis.\n\n2- Gametes fuse in pairs to form diploid cells called zygotes (fertilization).\n\n3- Repeated mitotic divisions of the zygote forms embryos.\n\n4- And the embryo develops into a new individual.\n\nSooo simple!\n\n====================\n\nCharacteristics of plant sexual life cycles-\n\nIt is same as animal sexual reproduction. Just that the technical terms and the methods of reproduction are a little different in flowering and non-flowering plants. I suggest you to read your textbook for the detailed terminology.\n\nIn plants-\n\n1- Diploid sporophytic cells divide by meiosis to give haploid gametophytic cells.\n\n2- Haploid gametophytic cells from male and female fuse to form the diploid zygote.\n\n3- The zygote then develops into an embryo and then to a full diploid plant body.\n\n* There are lots of finer details like the flowering system in flowering plants: pollens, ovules etc. and sporangia in non-flowering plants. I suggest you to study the life cycles of different bryophytes, gymnospermae and angiospermae to get the idea.\n\n================\n\nCharacteristics of fungal sexual life cycles-\n\n1- It involves fusion of two compatible sex cells/ gametes. The sex organs that produce gametes are called gametangia.\n\n2- The gametangia of fungi are unicellular and are surrounded by a sterile jacket. In fungi, there is a gradual reduction in sexuality from lower to the higher fungi.\n\n3- In the first stage, the cytoplasms of two sex cells fuse with each other but the nuclei do not fuse. The cell is thus called a dikaryon. (Plasmogamy).\n\n4- The nuclei then fuse to form the synkaryon. (Karyogamy).\n\n5- The diploid cell after that, produces haploid nuclei by meiosis.\n\nThere are broadly five types of sexual fusion in fungi.\n\nHere they are-\n1- Planogametic copulation. \nOne or both of the gametes are motile.\n\n2- Gametangial contact. \nThe two gametangia come together and the male gametangia forms a tube through which the male non-motile gamete is sent to the female gametangia.\n\n3- Gametangial copulation. \nThe gametangia themselves fuse together and lose their sexual identities to form zygospore.\n\n4- Spermatization. \nNumerous spore-like minute bodies (spermatia) are sent through various agencies to the receptive hyphae or trychogyne of female gametangium.\n\n5- Somatogamy.\nIn this mode, sex organs are not formed and the fusion occurs two vegetative cells resulting in the formation of dikaryon.\n\n=================\nI hope the above info helps.

Regeneration is when an being regrows a lost limb or other body part. Some lizards can regenerate their tails if they break off. (Although usually smaller.)\n\nPlants reproduce through sexual means, but they do not have sex. (That would interesting.) All that means is two individuals can reproduce which each other, although it is possible for a flower to reproduce with itself.  Pollen is basically their sperm and travels from one plant to another through insects, like bees, and wind. Then the flowers die and they form seeds. Some plants, like pine trees and ferns reproduce with spores, which work in roughly the same way.\n\nIf you're interested in all the techincal terms that I didn't use, check out the source.

I would have to answer that you're asking the wrong question!  \n\nThe explanation of how a plant or animal can develop asexual reproduction isn't going to help you better understand incremental changes via evolution; what you really need to understand is how a plant or animal can develop sexual reproduction. \n\nLooking at the first, microbiological life, asexual reproduction - i.e. cell division or 'budding' -  was the first and most essential form of reproduction. It took century upon century for more complex life to develop and specialize; and, for the mechanisms of sexual reproduction to develop and become established. \n\nThe change from asexual to sexual reproduction would indeed have been  massive, but it doesn't follow that it had to be sudden. When scientists look at species and evolution, they will generally say that one species was more successful at adapting to their environment than another. \n\nIt seems that the ancestors of many plants and animals developed sexual reproduction mechanisms, and they were more successful in competing with other animals for food/territory, over an extended period of time. The less successful ones died out long ago.\n\nSo - it may not be totally accurate to say, "reproduction either works or it doesn't." A better statement would be, "evolutionarily speaking, changes in species over time may cause one method of reproduction to become less successful than another."  \n\nHaving said that: there are other scientists who agree that evolution isn't always slow and gradual; they argue that sometimes evolution happens occasionally in a sudden and dramatic way, when one species splits to become new species - generally the new species are created when one population becomes separated by geographic boundaries. \n\nI'd strongly suggest reading the Wikipedia article (linked below) on Stephen Jay Gould for an evolutionary point of view which counters the slow evolution methodologies advocated by Dawkins; as well as the articple on evolution itself - which looks at the development of the understanding of evolutionary principles and their historical context.

I scanned a diagram I have into the computer, I hope this helps:\n\nhttp://i74.photobucket.com/albums/i267/Miles_Tails_Prower__/Aminals007.jpg\n\nBy the way Crimedog, you are thinking of Mitosis.  Meiosis is for sexual reproduction while mitosis is the asexual reproduction of eukaryotic cells.  (yoo-ku-rO-tic - cells with membrane-bound organells)

A flower is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called sperms). The flower structure contains the plant's organs, and its function is to produce seeds through reproduction. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. After fertilization, portions of the flower develop into a fruit containing the seeds.\nThe function of a flower is to mediate the union of male and female gametes. The process is termed pollination. Many flowers are dependent upon the wind to move pollen between flowers of the same species. Others rely on animals (especially insects) to accomplish this feat. The period of time during which this process can take place (the flower is fully expanded and functional) is called anthesis.
