yes they are. Seeds are much more complex than spores.\n\nhttp://en.wikipedia.org/wiki/Spore\n\nhttp://en.wikipedia.org/wiki/Seeds#Seed_structure\n\nyay take a look!

A corm is a short, thick, vertical underground stem that survives from one season to the next in a dormant state. The second season it produces one or more aerial stems and also one or more new corms. The new corms store food produced by the growing plant and then go through the next dormant period to produce their own plants and corms the following season. The “bulbs' of gladiolus are actually corms.\n\nPart 2 of your question\n\nVegetative reproduction is a type of asexual reproduction found in plants also called vegetative propagation or vegetative multiplication. \nThe problem of sex\n\nIn sexual reproduction, a new organism is formed by the fusion of two gametes. It is to be contrasted with asexual reproduction, in which females produce offspring without any male contribution; the female's gametes develop directly into female offspring. \n\n• In sexual reproduction, the sex cells - eggs and sperm or pollen - are produced by a reduction division and the gametic fusion restores the original chromosome complement. \n\n• In asexual reproduction, there is either no reduction division (apomixis) or the product cells of one individual's reduction division fuse together again (automixis). Asexual reproduction is rare, but occurs in species such as dandelions (pictured opposite).\n\nIt is easy for a mutation to convert meiosis into mitosis, and thus a sexually reproducing into an asexually reproducing female. \n\nIf the loss of sex would be relatively easy, why is sex maintained? \n\nAlthough some species do reproduce asexually, the majority are sexual. So there is probably a selective advantage to sex in most species. \n\nThis advantage, moreover, must be large, because it has to overcome an automatic two-fold cost of sex, relative to asexual reproduction.

Sexual reproduction in plants is described in Wikipedia as;\n\nIn flowering plants, a stamen produces gametes called pollen grains, which attach to a pistil, in which the female gametes (ovules) are located. Here, the female gamete is fertilized and develops into a seed. The ovary, which produced the gamete then grows into a fruit, which surrounds the seed(s). Plants may either self-pollinate or cross-pollinate.\n\nYou can also find out more here \nhttp://en.wikipedia.org/wiki/Plant_sexuality

General\n Both are stationary and produce spores/seeds for reproduction.\n Both go through an alternation of generations.\n Both are classified at the nost basic level by method of reproduction.\n Many plants and fungi have asexual as well as sexual reproduction methods.\n\n plants=photosynthesis\n fungi=feed on living or once living material (unable to photosynthesize)\n\n\nTry making a chart with fungi in one column and plants in the other. Then compare the different information you have.

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.

Because some bacteria produce spores as a way of encapsulating their genetic material in times of stress, and as they are dying. New, rapidly dividing cells in a new , nutrient rich, culture do not need to produce spores. As the nutrients are used up, the bacteria will begin to produce spores to conserve the genetic material. These spores will lay dormant until placed in the correct environment, and will then revive to grow into new bacteria. Some spores can survive autoclave sterilisation in this way - so its a very effective species survival strategy.

Spore bearing would be acceptable in this case.  Also, moss is not a fungus.

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).

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.

Live bacteria seems unlikely. Bacterial spores, no problems.\n\nYou would have more luck trying to isolate fungi.

Everyone who answered already are blithering idiots. All fungi produce exoenzymes that break down the substrate (food) that their spores land on. Similar to flies, fungi produce these enzymes to break down foods into simple sugars that they can then easily absorb. Different fungi produce different exoenzymes. Therefore, if a fungal spore happens upon a particular substrate (food) for which it doesn't produce the proper exoenzyme, it will not grow on that food. The best substrates are potato extract agar and malt extract agar.
