What conclusion about plant growth can be drawn by combining the functions of gibberellin and cytokinin?
Answer and explanation
Correct answer: Both cell division and stem elongation are important in plant growth
Gibberellin and cytokinin are plant hormones, but they promote different growth processes. Gibberellin mainly stimulates stem elongation, whereas cytokinin promotes cell division and supports the formation of new cells. Therefore, combining their functions shows that plant growth depends on both an increase in cell number and an increase in cell length. Options B, C, and D incorrectly describe these hormones.
