Also, do they have some sort of sensing of any kind? (plants always seem to grow around there envirement as if they know what's around them)

To feel pain, you will need a central nervous system and and a brain advanced enough to know that what you are feeling is pain. most plants do not posses a central nervous system, much less a brain. Therefore the plant cant "feel" anything, and is merely a collection photosynthesizing cells among others that chemically react to the photon radiation from the sun light. where ever the radiation is strongest is where the cells will migrate, making the plant appear as though it is consciously leaning toward the sun. If the cells while spreading or "growing" run into an object, they obviously have to grow on or around it since they can grow through it. their are some plants however that do have a collection of simple nerves and motor functions that actually react to touch, such as the Venus fly trap and the sun dew. the nerves aren't fibrous and veiny like the ones in humans and animals, instead they are made of a collection of special cells that are conductive to electrical impulses.

I am highly skeptical of this notion.  However, they affect the moisture content of the air through the transfer of moisture into/out of leaves through holes on the underside called stoma.  Maybe they were referring to heat caused by light shining on the leaves.  This heat would result from absorbance of light.  This heat would radiate off the plant into the air and would warm the air around the plant.  That's all I can hypothesize.

Well, technically plants spend carbon dioxide and produce oxygen.I think... I would think that since most plants continue to grow until they die, that the bigger they get, the more carbon dioxide they use, and the more oxygen they produce.

i would assume it would have something to do with not having to stake plants up, etc..they would grow straighter, because their fruits, branches, etc would not weigh them down as much.  i.e. tomatoes would not have to be staked up but would naturally grow straighter and keep their fruit off the ground.

not exactly...they detect unusual higher-spectrum dynamic variables(like ultraviolet rays)using the same old colors we see to detect "Visible Light".

Yes, there are. They are called Phytohormones(plant hormones). Some promote seed dormancy. (Cytokinin, Gibberelins, etc,)

yes but they are not aware that they are using the knowledge from science studies. example the herba plant they prescribed to cure a certain illness has scientific proofs because of the special compound present in the particular plant.

Yes they can. Their senses are much more acute than ours. They can hear the rumblings below and the first to be aware are birds. This also triggers off the bears instincts that something abnormal will happen though they don't know exactly what.

it's a hard question to answer, cuz same as you can't be certain they don't, you really can't know for sure if they do !! Although I can't say they exist ... i don't really see it impossible ... they "might" exist ;)

scent and color. Insects see color.

OK, I like this question. :-) Bear with me, what I'm about to share has a point to it all ... You walk through an element all the time. The element I speak of is air. Its so fine in its molecular construction that you don't even realize its there. You can walk through water, but with greater difficulty, beause of its density. You can't walk through a brick wall, because its molecular make-up is to dense. Now, a dog perks up its ears. It hears a sound. But you can't hear that same sound. Owls can see well in the dark, but you can't. A deer sniffs the air because it smells the metal rifle the hunter carries, but you can't smell that. There are colours that you can't detect, because of the way your eye is constructed, but that's not to say that the colour isn't there. Now, going from here ... WHAT IF ... Something existed that was of a colour you couldn't see, made sounds that you couldn't hear, gave off a scent that you couldn't smell, and was constructed of a physical substance that you couldn't feel? (Remember, 100 years ago there were only 40+ substances on the Table of Elements, NOW there's well over 100. How many more might there be?) Yes, dragons exist. They just fall into the above catagory. They have intelect similar to humans, and are able to manifest in a way that allows us to know they're there. Which is why they show up historically all around the world and throughtout time. But, given their physical "construction" no paleontological evedince will ever be found to substantiate this. This is my opinion, and its based on experience. ~ Peace & Blessings ~

In order to withstand pressure, their cells must counterbalance the extreme pressure outside. Also, animals at such depths are generally colourless and are blind. They navigate by sound.

Think about the adaptations that allow a cactus to live in a desert.  Could a piece of pondweed live there?\n\nWhy do fir trees grow where it is cold?   Could an oak live there?

Nope, just like tomato seeds and banana seeds don't. The reason is,they pass through your system and the feces provide an ideal growing environment for a seedling.

Honey bees are attracted to plants with bright colours however they cant see red. All the bees (females  called workers) will go out and once one finds a spot with alot of flowers the bee marks that area with a scent returns to the hive to get the other bees so they dont waste time looking for flowers.

Well, its not really "music" that make plants grow. Its the sound waves in the air that trigger the plants growth hormone. In a sense, the plant thinks its being eaten, so it "wants" to grow. Talking to it, any kind of noise is helpful in their growth!

Plants must have light to grow.  It doesn't necessarily have to be sunlight. Artificial light is a great to grow most plants too.  Photosynthesis is what causes plants to exchange necessary nutrients to create growth but each have unique abilities to utilize whatever light source is available.
