meristem and roots
stems and leaves
roots and stem
leaves and roots

Answer 1

the main plant organs at work during growth mediated by growth hormones are meristems, roots, stems, and leaves. Growth hormones regulate leaf development, expansion, and senescence, as well as stem, fruit, and seed growth. Meristems, which are regions of the plant where cell division occurs, are also affected by growth hormones. Additionally, hormones, especially auxin, play an essential role in controlling growth rate, branching, and lateral root formation in roots. Therefore, all plant organs, including roots, stems, leaves, and meristems, are involved in plant growth mediated by growth hormones.
