Question

35)
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.

Explanation:

To determine how gibberellins affect other plant parts, we analyze each option:

• Option F: Gibberellins are not absorbed through stomata (stomata are for gas exchange, not hormone absorption) and don't attach to chloroplasts. Eliminate F.
• Option G: Gibberellins (plant hormones) are transported via vascular tissues (xylem and phloem) to other plant parts. This is consistent with plant hormone transport mechanisms.
• Option H: Gibberellins don't become concentrated during mitosis; mitosis is cell division, not related to hormone concentration in this way. Eliminate H.
• Option J: This describes a pathogen's life cycle (like a virus or fungus), not gibberellin action. Eliminate J.

Answer:

G. Gibberellins are transported through vascular tissues to other parts of the plant.
