Describe (HT only) the use of gibberellins to increase fruit size.

In the subtopic Use of plant hormones (HT only), this learning objective focuses on describe (HT only) the use of gibberellins to increase fruit size. Within Plant hormones (biology only), students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include fruit size, gibberellins, and HT only. gibberellins means plant hormones that promote growth and are used to increase fruit size. Avoid students often confuse gibberellins with auxins and incorrectly state that auxins are responsible for increasing fruit size; instead students should remember that gibberellins specifically promote fruit size increase, while auxins have different roles such as promoting cell elongation and root development. For exam answers, focus on how gibberellins are used to increase fruit size in agricultural practices.
