The Colorado Spruce may share similar properties to Lodgepole Pines. Look up some information on the 1988 fires of Yellowstone.\n\n"Many of Yellowstone’s plant species are fire-adapted. Some (not all) of the lodgepole pines (Pinus contorta), which make up nearly 80% of the park’s extensive forests, have cones that are serotinous sealed by resin until the intense heat of fire cracks the bonds and releases the seeds inside. Fires may stimulate regeneration of sagebrush, aspen, and willows, but the interactions between these plants and fire is complicated by other influences such as grazing levels and climate. Though above-ground parts of grasses and forbs are consumed by flames, the below-ground root systems typically remain unharmed, and for a few years after fire these plants commonly increase in productivity.\n\n\nhttp://www.nps.gov/yell/nature/fire/

In general a cone, but not exactly.  A teepee doesn't actually go to an exact point and the large end is less a circle than it is an oval.

You can see some nice picures of pine needles here:\nhttp://www.metla.fi/eu/icp/phenology/pine.htm\n\nActually your question is kind of unclear, and it may mean that you are looking for the evergreen trees like pines, in which case I think you mean conifers:\nhttp://images.search.yahoo.com/search/images?p=conifers&ei=UTF-8&fr=sfp&fl=0&x=wrt

It dies.\n\nThe outer layers of bark - and just under that - are the vascular like systems that transport water and nutrients to the leaves - just like your veins. Now, imagine someone cuts all your veins and arteries up - you bleed to death. Even if the tree does not appear to "bleed" ringbarking can still kill if it stops the flow of water/nutrients from the roots and leaves and back again. \n\n... or something. Try wikipedia.

How cold?  I live in Colorado and lots of plants survive through the winter.  They are dormant during the cold months though.

Depends upon the tree and the conditions.  Pussie willow shoots (especially green ones) can be placed in a container of water and will actually grow roots.  These can be planted in the ground to form new trees or bushes.  Weeping willows do the same.\nExperiments have been done with whole evergreens to determine the amount of transpiration (of water vapor) from their needles (the trunk of the tree being placed in an aqueous solution of dilute minerals).  Based upon the oxygen gas generated if the tree is in sunlight), the tree does continue to live for some time.

As a plant grows up ward it bears leaves on the sides of the upright stem.In the axile of every leaf( the point where the leaf stalk is attached to  the stem.), there is an axillary bud.This bud IS THE STARTING POINT OF A NEW BRANCH.\nAs long as the main stem continues to grow actively these axillary bud are dormant.But when the main stem stops growing or becomes slow in its growth, the axillary buds are activated by certain growth hormones that are produced naturally in the pant and the meristem tissue(embryonic or formative tissue) inside the buds begin to multiply and gradually begins to develop in to a side branch. It may be an ordinary vegetative branch like the main stem itself or a flowering branch.It depends upon the season,the age of the plant and the type of the hormone.\nIn Nutshell: In plants the branches develop from the meristem tissue.They are present in the buds and activated by hormones.\nFor more than this get hold of a proper botany book ( anatomy book) and study yourself.

Female pine cones are the ones that you think of as an actual pinecone. They are the large dark brown woody structures which hold the seeds. People commonly use them in crafts for kids (ie making turkeys at Thanksgiving).\n\nMale pinecones are small in comparison w/ female cones. They are usually long, thin & light brown in appearance. I say usually b/c some species have shorter stockier looking male cones. They are usually found in clusters. They are the ones covered w/ pollen this time of year so they may look green. Most people don't recognize them as cones b/c their structure is so much different than the female cones.\n\nHappy cone hunting. LoL\n\n:)

1. Wind- Some seeds are carried to a new place by the wind.\n\n2. Water Dispersal- Fruits which float such as those of the water lily and the coconut palm are carried by water.\n\n3. Animal Dispersal- Some seeds that are ingested by animals can be digested and later excreted out far away from the parent plant.  Some seeds also have burs so they can attach themselves to animal fur only to later be dropped.\n\n4. Explosion- Some plants have pods that explode when ripe and shoot out the seeds.\n\n5. Fire- A number of species of pine have cones that only open after a fire. These are called serotinus.  Jack pines have cones that are held closed by a resin sensitive to high temperatures. These cones will not open to release their seeds until a critical temperature is reached.

The bark is on the outside of the tree and is usually fibrous and/or corky in nature. It is produced continually and can be either persistent or can be shed regularly (as in many smooth-trunked trees). The reason "ring-barking" will kill a tree is that if all the true bark (ie, the living, growing part, not the dead corky/fibrous part) is damaged then phloem transport of nutrients (products of photosynthesis) from the leaves to the roots is stopped and the roots will die and so will the plant. (The sapwood is xylem and transports water and minerals to the leaves)

Answers 1-3 are correct, its is a gymnosperm which produces a cone.  You are wrong by calling it a fruit as only angiosperms have fruit.

The tree will provide some radiative insulation on a clear cold winter night.  All objects radiate heat at a rate based on their temperature.  Out in the open, you will frost up quick just like the ground.  That's because your body is radiating heat to the cold of outer space much more quickly than space radiates back to you.  Since the tree is warmer than space, it will send more infrared radiation back your way to help compensate for your own heat loss.

no. You don't count the rings on the bark. YOu count the rings from a cross-section of the trunk, and the ways to do that is to cut the tree down, which kills it, OR take a core sample, which may or may not kill it.\n\nThe rings from the trunk of the tree are created by the growth of the season (when the new soft wood is created into old hard heartwood), so basically it is going from "old bark to new bark". The thicker the ring, the more growth.\n\nFor the love of everything, do not listen to anybody that says yes. The bark has no rings. The trunk is the only thing that has the rings. Humans have killed a bristlecone pine tree dating OVER 4500 years old! \n\nfor more information go to:\nhttp://www.sonic.net/bristlecone/dendro.html\nhttp://www.pbs.org/wgbh/nova/methuselah/treering.html\nand to really show you some good pic on the tree rings\nhttp://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artjan02/treering.html

The pine; it's got cones.

its a wonder\n\n!\n\nto know it\nThe seeds are carried away from the mother plant by animals called dispersers. In some cases the animal carries away an entire fruit, in other cases the animal is carrying seeds alone. The animal usually feeds on the fruit (ovary wall), but "tosses" the seeds (or passes them through its digestive system). This assures that seeds end up far away from the "mother" plant, where they can develop without competition from "mom."\n\nHaving been taken away from the parent, it is time for the seeds to sprout or germinate. Seed germination is defined as the emergence of the radicle through the seed coat. Common garden seeds germinate if given just water and reasonably warm temperatures.\n\nWild species usually have some kind of deeper dormancy to avoid sprouting in late summer or fall when the seeds are commonly dispersed. This assures that tender seedlings are not frozen at a young age by the approaching winter. Instead the seedlings do not appear until warm weather arrives in springtime.\n\nIf a species has evolved a very thick seed coat, it may require scarification of that seed coat before water can enter the seed and initiate germination. Perhaps the coat has to be gnawed at by animals, or frozen and thawed repeatedly to crack the coat, or rund down the rocks in a stream bed or up beach in pounding surf to wear the coat down. Perhaps the seed is swallowed whole by the disperser. The thick seed coat protects the dormant embryo as it passes through the animal's digestive system. The weakening of the seed coat through digestion means that the seed is ready to sprout when it gets deposited (along with a bit of fertilizer) by the disperser somewhere new in the environment. Yet other seeds require a brief exposure to fire to scarify the seed coat.\n\nIn species with thin seed coats, light may be able to penetrate into the dormant embryo. The embryo may then either use the presence of light or the absence of light to trigger its germination process. Small seeds with thin seed coats are likely to use light as a signal for germination. If these are buried shallowly enough for light to hit the seed, then its germination will initiate and before it runs out of reserves, its cotyledons will be doing photosynthesis. If the small seed is deeply buried it does not germinate; it has no idea how deep it is buried and may not have sufficient reserves on board to make it to the surface before they run out. Evolution favors shutting down germination in the dark for those species. For large-seeded species, the opposite may be true. There is an advantage to having your reserves buried before starting to germinate...otherwise the sprout just acts as a flag to say..."come and eat my nutritious seeds here on the surface." Evolution favors a large seed with lots of investment in storage to wait until it is buried before sending up its shoot. Such a seed will key in on darkness rather than light. In laboratory you will see an example of each of these kinds of evolutionary adaptations!\n\nIn yet other species, the embryo is fully developed when the seeds are dispersed. They need to be deposited in soil that possesses fungi that serve as host to the seed and seedling until the development is completed and the seedling is big enough to grow on its own. Trying to sprout many orchid seeds in common garden soil is futile...the required fungal hosts are not present...so leaving wild orchids where they naturally grow is the best idea.\n\nIn most species of wild plants the mother invests the seed with abscisic acid. This hormone makes the embryo dormant until environmental conditions and native enzymes permit the abscisic acid to be broken down inside the embryo. The enzyme required is present in the embryo in the fall, but it is inactive until activated by low temperature. About four weeks at 4°C is required to activate the enzyme and degrade all the abscisic acid in the embryo. This cold

Wintergreen sparking, it's believed, is actually a three-step process. Step One: When you shatter the sugar crystals with your teeth, electrons (which are negatively charged) break free. As a result, the atoms in which the electrons were formerly embedded become positively charged. In what amounts to a subatomic game of musical chairs, the free electrons dash around madly trying to find a new home. \n\nStep Two: Meanwhile, as the sugar crystals disintegrate, nitrogen molecules from the air attach themselves to the fractured surfaces. When the free electrons strike the nitrogen molecules, they cause the latter to emit invisible ultraviolet radiation, along with a faint visible glow. \n\nStep Three: The UV radiation is absorbed by the wintergreen flavoring, methyl salicylate. This then emits the fairly bright blue light you see. Pretty complicated, I admit. Clearly the planners in the Pentagon weren't the first to be obsessed with high-tech gimcracks.
