What's plant survival strategy?

spread as many seeds as possible and hope for the best

Gingko tree is winning.

>can plants feel pain?
no
>Why plants can't move?
Some can move their leaves, e.g. http://en.wikipedia.org/wiki/Mimosa_pudica
If you meant why they can't walk, that's because they don't have legs, don't have muscles, don't have a nervous system.
>Why they are fucked by simple things such as fire unlike animals?
Because every living being is fucked by fire. Burning animals die too.
>Why they didn't evolve defense (movility) against fires?
Some plants evolved to live in regions of forest fires: http://en.wikipedia.org/wiki/Pyrophyte
>What's plant survival strategy?
plentiful reproduction

why animals didn't develop photosyntesis?

>can plants feel pain?
Well they can certainly be aware that something is wrong and e.g. induce necrosis.

>Why plants can't move?
But they do move.

>Why they are fucked by simple things such as fire unlike animals?
What animals aren't fucked by fire?

>Why they didn't evolve defense (movility) against fires?
Kind of difficult to move so much when you have roots and stuff

>What's plant survival strategy?
Depends on species, obviously

Here's a legit question:

Why plants can't fix nitrogen?

I want to mean a forest fire.

Why plants can't fix nitrogen?

Because of some kind of bacteria in the root nodules of legumes?

Yes but all plants absolutely require nitrogen and it's so plentiful in the air. Yet, since plants can't fix it, it's most often a growth limiting factor. Why they didn't evolve the ability to fix it?

Most anaerobic bacterial organisms when placed in extreme environments (ie. near geothermal vents, oxygen poor environments) often evolve their respiratory mechanism to swap from one final proton acceptor to another. So instead of producing water, they produce hydrogen sulfide, or ammonia.

Plants have never grown in oxygen poor environments and being far more complex organisms, are not subject to the same speed of natural selection that bacteria are, and thus its very difficult to envisage a position where they did.
The end product of the hydrolysis of ATP is hydrogen which ultimately must be pushed onto an electron acceptor (O, S, N, even P) in order to regenerate NAD and allow respiration to continue.
