What are the differences between auxins and gibberellins?
The main difference between auxin and gibberellin is that the auxin promotes the growth of the shoot system whereas gibberellin promotes stem elongation, germination, and flowering. Furthermore, auxin plays a role in apical dominance whereas gibberellin has no role in apical dominance.
What are auxins gibberellins and cytokinins?
Plant Cell Growth regulators (e.g. Auxins, Cytokinins and Gibberellins) – Plant hormones play an important role in growth and differentiation of cultured cells and tissues. The Cytokinins induce cell division and differentiation. Cytokinins promote RNA synthesis and stimulate protein and enzyme activities in tissues.
How is auxin different from cytokinins?
In the root meristem, auxin induces the meristematic cell division, whereas cytokinin promotes the cell to switch from the meristematic to differentiated state through inhibiting auxin signaling.
What is the similarity between auxin and cytokinin?
| Auxins | Cytokinin |
|---|---|
| Promotes cell elongation | Promote cell division in plant roots and shoots, leaf ageing and enlargement. |
| Plays a major role in phototropism, geotropism and hydrotropism. | Moves from roots into shoots and thus signals lateral bud growth.. |
Where are auxins and gibberellins?
They play an important role in the regulation of plant growth. They are mainly produced in the apical meristem of shoots, young leaves and seeds.
What is the function of auxin and cytokinin?
A main feature is that as auxins and cytokinins are critical to regulate cell division and differentiation, these hormones are therefore tightly associated with the formation of new organs such as lateral roots, nodules on legume roots in response to rhizobia, as well as galls for example in response to A.
What is the common function of auxin and gibberellins?
The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant is one of the main places that auxin is produced. Gibberellins are growth hormones that stimulate cellelongation and cause plants to grow taller.
What is the function of gibberellins?
Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence. GAs are one of the longest-known classes of plant hormone.
What is the main function of cytokinin?
Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence.
