how does the frangipani plant disperse their seeds?
101408
Frangipani fruit consists of a pair of leathery follicles (pod-like things), although the trees rarely fruit in cultivation. Seeds are winged and are released when the pod opens (see second link).

[edit] Courtship and mating\nUsually, the instinct to pass on genetic material drives young wolves away from their birth packs, leading them to seek out mates and territories of their own. Dispersals occur at all times during the year, typically involving wolves who reached sexual maturity during the previous breeding season. It takes two such dispersals from two different packs for the process to take place, as dispersing wolves from the same maternal pack tend not to mate.[15] Once two dispersing wolves meet and begin traveling together, they immediately begin the process of seeking out territory, preferentially doing so in time for the next mating season. The bond that forms between such wolves often lasts for the shorter of the two lifetimes, with few exceptions.[16]\n\nDuring the mating season, breeding wolves become extremely affectionate with one another in anticipation for the female's ovulation cycle. Overall, pack tension rises, as each mature wolf begins to feel the urge to mate. In fact, during this time, the alpha male and alpha female may be forced to aggressively prevent other wolves from mating with each other.[15] Under normal circumstances, a pack can only support one litter per year, so this type of dominance behavior is beneficial in the long run.[15]\n\nWhen the alpha female goes into estrus, a phenomenon that occurs once per year and lasts 5–14 days,[17] she and her mate will spend an increased amount of time in seclusion. Pheromones in the female's urine and the swelling of her vulva let the male know when his mate is in heat. She will be unreceptive for the first few days of estrus, during which time she sheds the lining of her uterus. Once the female begins to ovulate, mating occurs.\n\nThe male wolf will mount the female firmly from behind. After achieving coitus, the two form a copulatory tie once the male's bulbus glandis— an erectile tissue located near the base of the canine penis— swells and the female's vaginal muscles tighten. Ejaculation is induced by the thrusting of the male's pelvis and the undulation of the female's cervix. The two become physically inseparable for anywhere from 10–30 minutes, during which period the male will ejaculate multiple times.[18][19] After the initial ejaculation, the male may lift one of his legs over the female such that they are standing end-to-end; this is believed to be a defensive measure.[19] The mating ordeal is repeated many times throughout the female's brief ovulation period, which occurs once per year per female, unlike female dogs, with whom estrus usually occurs twice per year.

The human body is simply not capable of fully digesting some foods.  Many seeds for example (like corn and fruit seeds) have evolved to be hard shelled and resistant to digestion in birds and mammals to accomplish dispersal.  The plants that produce seeds often package them in a nutritional "gift", such as a fruit.  An animal eats the fruit, moves elsewhere, and defecates the seed out in another area.  A wonderful adaptation for plants that are sedentary and have no other way of dispersing their seeds.

some plants have hook shaped fruits.. it can hook onto animals n be carried off to different places\n\nDandelion has light featherlike seeds exposed to air that can be blown off with the wind\n\nPlants near waterbodies have seeds that can float on water.. so again they can be deposited in far off places\n\nThere r various other adaptations in the links below.. check em out..

It's a matter of survival.  Only a small percentage of seeds produced by plants will actually grow into mature plants.  Some won't germinate.  Some won't wind up in a place where they can germinate.  Some will be eaten.  Plants produce so many seeds so that enough of them will grow into mature plants to ensure survival of the species.

Weeds are plants that are not native to an area. Usually the plant will have gotten from one part of the world to another by humans who wanted cool garden flowers or scientists who wanted to do test and so on. Weeds spread around by way of birds, bats and other creatures eating fruits of a plant as food and then poop out the seeds when they are flying around. Seeds are too tough to be digested and the poop acts as a little packet of fertilizer. And presto, your lawn is covered.

Taking pollen grains from one plant and puttig them on the stigma of flowers of onother plant is cross pollination. When this happens properties of two plants get mixed so a new improved plant can be produced. Bees come in cotact with pollen grains of one plant when the collect the nector and when they vist other plant they leave pollens in the flowers in process pollinate them.\nTo attract bees, plants produce nector and scent and when bees visit these flowers they are pollinated so more fruits are produced\nThis realtionship for the benefit of both hence it is called symbiosis.

Seeds have a hard outer shell which withstands the cold winter and protects the young plant inside.\nIt is broken down enough by the winter weathter that in the spring when the weather warms and signals the young plant inside to grow, it is not hard enough to cause the plant not to be able to break free of it.

You need to get the sperm to the eggs and with an "army " of sperm, its more likely that some of it will eventually make it past all of the factors that might cause it from not reaching its target... such as when pollen is on a pollinator, some of it is usually lost in flight or just in the regualr movement of the animal that does that job. some plants are pollinated by the wind and the more that is released increases the  chance that some of it will reach the egg. Eggs are usually very close to the adult version of the plant or even within the plant before they are fertalized so they are mainly stationary... with more chances to reach the egg it increases the fecundity.

It's related to a chemical called a germination inhibitor that prevents the seed from sprouting... but that chemical can go away prematurely... as seen here:\n\nhttp://www.cookingforengineers.com/article.php?id=57\n\nRead more:\n"Until then, they remain dormant. Germination inhibitors are part of the make-up of every seed. They actually prevent a seed from germinating until its chances of survival are good. Usually chemical in nature (five per cent of seeds are simply waterproof, dormant until their seed coat cracks), germination inhibitors put a seed into dormancy. Without these, a tomato seed, for example, would spout right inside the fruit of the plant that formed it, where there is moisture and warmth, good conditions for germination. Inhibitors give a seed time to travel away from the parent plant, and allow it to overwinter, or be stored, giving that seed the best possible chance to reproduce successfully and to spread. Germination inhibitors `wear off’ over time, allowing a seed to sprout the next year."

The fertile regions on fronds that bear sporangia are known as receptacles, and the group of sporangia on a single receptacle is called a sorus. In many species, but by no means in all, the sorus is covered during development by a flap of tissue called an indusium. The shape and arrangement of the sori are different in different species.\n\nhttp://www.bbg.org/gar2/topics/botany/repro_ferns.html

There are Ceiba trees at the ruins ... they have pods with many seeds surrounded by a dense mat of cottony fibers. Does this fit? Or it could be a legume (bean-like seed?) of some sort or a member of Bignoniaceae (flat winged seed?). If it is 9 months old it hasn't faced a full Canadian winter yet, I hope you are going to protect it!

to have a good idea have a look at the article below. hoppe it helps... it's a bit long but will have what you need properly explained...\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 absorbin

The answer could be (c), conifers.\nIn general, the plants that produce seeds without flowers are called Gymnosperms.  Conifers are gymnosperms.

There's this weed that had poisonous spiky hairs on the thick stem, and if manhandled, spreads it's seeds really fast and the hairs can cause tumors in the hands. Also really hard to pull up and the root can grow more plants. And it's in the U.S.! Wyoming!
