An experiment is conducted on three plants of the same species:

  • Plant 1 is not treated.
  • The tip of the main shoot of plant 2 is cut off.
  • The tip of the main shoot of plant 3 is cut off. Afterwards a phytohormone is applied to the cut surface on the plant.

The plants are now placed under observation:

  • The main shoot and the side shoots on plant 1 grow.
  • The main shoot on plant 2 does not grow. The side shoots grow.
  • The main shoot on plant 3 grows. The side shoots do not grow.

These results are generally applicable to this species of plant.

Which of the following two statements is/are correct?

I. The phytohormone promotes the growth of the main shoot of this plant species.
