In relation to this question, what would plants do if they were taken from their environment to another gravity level, in particular zero g.
For example would the daisy manage to grow higher because it doesn't need to make so much effort to hold its head up? Would its form change?
What happens to a tree if it gets planted in an low or zero g environment? What would happen if it was already established in normal g and then sent to space?
Or in short: What factors of a plant growing are affected by low gravity?
EDIT: Liath did point out the breeding of plants in low or micro gravity, but my question was also about: How would a full grown plant react? for example a tree in the middle of its life span. If it is ripped out of its planet and put on a generation ship to regenerate the air.
