Auxins are chemicals exist in plants to stimulate growth. When sunlight hits one side of the stem of a plant, the auxins move away and down from the sunlight. This causes the 'dark' side of the stem to grow faster than the 'lighted' side, which causes the stem to lean towards the source of the light.

Where are auxins produce?

Auxins are substances that promote stem elongation and inhibit the growth of lateral buds. They are produced in the stem buds and root tips of plants.


What is the thing that plants do this towards the light?

Plants exhibit phototropism, which is the process of growing towards a light source. This behavior allows plants to maximize their exposure to sunlight for photosynthesis, which is essential for their growth and survival.


Are auxins transported in xylem or phloem?

Auxins are primarily transported in the phloem tissue of plants. They can move in both directions within a plant using the phloem, allowing for the long-distance signaling that regulates plant growth.


How does the plant responds to Auxins?

Auxins promote cell elongation in plants, leading to increased growth rate. They also help in phototropism, gravitropism, and apical dominance. Additionally, auxins are involved in root development and lateral root formation.


Can auxins be produced naturally or can they be made in a laboratory?

Auxins can be produced naturally by plants to regulate growth and development. They can also be synthesized in a laboratory for agricultural purposes, such as promoting root growth in cuttings or controlling fruit ripening.


Where are auxins produced in plants?

Auxins are primarily produced in the shoot apical meristems, young leaves, and developing seeds of plants. They are also synthesized in the root tips and young stems.
