No it comes from the mineral Halite.
Depends entirely upon the seed and how much salt.
anything that has seed in it
yes, celery salt is typically made from the seed mixed with (sea) salt, you could technically dry the celery stalk and mince it and mix it with salt as well, but what they sell in the stores is typically the seed which imparts the similar slightly bitter celery flavor as the stalk (the flavor coming from the oil in the seeds).
It depends on what amount of salt you use and the amount. I am presuming that you are using coking salt. Salt kills plants, it wont kill your bean seed with a tiny amount but the larger the amount the bigger the risk of it dieing.
yes
first leaves that come out of the seed
Pure celery salt contains finely ground salt and celery seed. There shoud be no wheat gluten in it.
The salt inhibits germination of seeds. Although a little bit of salt does help the seed to grow more than if it just had normal water.
Your seed crystal could be anything.However, if you are trying to grow a "pure" crystal then you should choose something that is not going to be a problem with your final compound. For example, using a pure form of the crystal itself.So seed salt water with SALT. But you might try a grain of salt to seed other crystals too.
