Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots.
How are gibberellins able to affect other parts of the plant?
F Gibberellins are absorbed through the stomata and attach to chloroplasts.
G Gibberellins are transported through vascular tissues to other parts of the plant.
H Gibberellins become concentrated within the tissues of the plant during mitosis.
J Gibberellins become modified once they infect healthy cells and are later released to infect
other cells.
