Question

Give a schematic diagram to explain the effect of auxins in different parts of the plant.

Answer 1

Answer:

Auxins are the plant growth hormones that control the growing parts of the plant, stimulate cell elongation, differentiation of xylem and phloem, fruit development, apical dominance etc.

Auxins influence gibberellins that promote cell elongation and thus increases plant length. They increase the distance between nodes thus spacing the branch points. Auxins control seedling orientation and always move away from light and downward due to gravity. In areas, where auxin is highly concentrated, cell growth is more. Auxin when applied, also stimulate root branching by initiating roots at the cut stem.

Answer 2

Auxins

Explanation:

Auxins are plant hormones that control the growth of the plant, stimulate cell elongation, differentiation of xylem and phloem, fruit development, apical dominance, etc. Auxins are responsible for gibberellins which promote cell elongation, hence help increase plant length. They influence the space between nodes and hence the branches. Auxin promotes growth of the shoot towards the light and the growth of the root towards gravity. In areas where auxin concentration is high, cell elongation takes place, thus stimulated growth at that point.

Please refer the attached picture for the diagram.
