the seed will start to grow with the right amount of elements eg:light,water,soil ect all the basic things needed for the seeds to grow.

About 14 days if conditions are right.
What are known in nature as helicopters are the seed pods so yes you can grow a tree from them, given the right conditions.

Yes, I believe conditions are right for that.
Dried beans are usually living, but dormant, and will grow when conditions are right. Water, soil temperature and so on.

A normal been seed is dormant (asleep) until the right conditions prevail to allow it to sprout and grow, but throughout it is alive.
Optimum moisture, temperature and aeration prompts a viable seed to sprout and grow. Later on it also needs a proper soil for getting the necessay nutrients.
yes.
Because you didn't grow it right.
1 - it takes a long time for the seed to get ready to open, 2 - but in the right conditions, the roots will split up quicker
