are seeds alive, i mean do they have living cells in them i mean? and if they do how long does a seed live.
how does a seed know when to start growing. what senses does a seed have and how do they work
thanks

it is a life form, the seed is an embryo with two points of growth, 1 forms the stem and one forms the roots . this is enclosed in a coat which provides food .. but there are many types of seeds which function in different ways
seeds do have a lifespan, generally 2 to 3 years if kept in a packet or box

seeds need water, oxygen, soil and light to begin the germination process (growing)

seeds are constructed of living cells, so they are alive. Seeds could die (decomposite) also like other living creatures.

I have insufficient knowledge to explain this process in more detail

you perfectly understand that research must be done to answer your question.

that is a good question dude, because its pretty hard to believe, that something living can endure that long in a state of not doing anything. but lots of them are very nutritious, so they are living off something while being protected in their shells. i feel like knowing more about it, just had the urge to know how wine is made and looked it up.

What if I place seed in ice would it be "active" after n years?

ok looked it up. there are deepfrozen seeds to buy, but their chances of working are not as high as freshseed

Some seeds can be 'reactivated' after being frozen but others dont fare so well.Its all to do with the moisture content of the seed to begin with.

does the svalbard seed bank replace there seeds every year, since they might die

If you know about seed banks why can you not look all this stuff up yourself dude?

" its pretty hard to believe, that something living can endure that long in a state of not doing anything."
I think the same thing about myself all the time.

more stuff i should be able to spout knowledge about.
in pure lamens terms... it depends, diffent spp have different requirements/life spans. many types of seeds can lie dormant in the ground for long periods of time, waiting for the right balance of conditions for thier germination to be successful.
some seeds need certiain conditions to have happened in a predetermined succession, ie. a period in deep cold(winter) followed by a period of dryness and then exposure to high temps, ie the spring/summer followed by a brush fire to make them germinate, when people collect seed and impose these condtions upon the seed its called strafication, i think. this is basically man playing nature to make the seed become viable so that we can grow it.
so in a very in-direct reply to ur question, yes seeds are living, they are effectivly embreos. the conditons upon which a seed 'decides' to become living differ between spp and the requirements of that spp. not very scientific or detailed answer as such but i been drinkin since 3pm, if you want more info let me know and i'm more than happy to look into it more, for my good and yours.
i study arboriculture btw so it is of interest to me.
