Plant Physiology

A. True: Auxins can induce parthenocarpy (fruit development without fertilization).
B. True: Plant growth regulators (hormones) can stimulate or inhibit growth depending on the hormone and concentration.
C. True: Dedifferentiation (loss of specialized structure and function) is necessary before cells can re-differentiate into new cell types.
D. False: Abscisic acid is a growth inhibitor, involved in stress responses like drought tolerance.
E. False: Apical dominance suppresses lateral bud growth, favoring growth of the main stem.
