7.
Abscisic acid (ABA) is a naturally occurring hormone in plants whose production is increased in the winter months. It has been found to disrupt the cell cycle, keeping the cells in the G1 stage. If ABA production stops, what would be the immediate effect on the plant?
a)
It would continue to grow in the winter and eventually die from exposure to cold temperatures
b)
It would lose its leaves in the winter and be protected from exposure to cold temperatures.
c)
It would continue to grow in the winter and evolve to thrive in cold temperatures
d)
It would cease production of fruits so none could be harvested for the winter.
