Plant Reproduction and Development fill in the xx?

I won't really do your homework for you, but I will give you a short version. First plants create hormones in order to survive in hot- cold conditions, reproduction, and growth. ABA is a stress hormone, IBA is a growth hormone, BAP is another growth hormone, And GA3 creates fruit development and the reproductive/ fruit stages which is triggered by DD. The growth hormones trigger the responses to light and darkness. Also sometimes they help determine the of the off spring. That is really what I am going to tell you. Look up all of the growth hormones and see what each one does.
