How do auxin's control a plants response to light?
Auxins play a crucial role in phototropism, the plant's growth response to light. They promote elongation of cells on the shaded side of the plant, causing it to bend towards the light source. Auxins help to redistribute growth hormones, leading to asymmetric growth and the plant's directional growth towards light.
How do auxins affect plant cells?
Auxins regulate cell elongation and division in plants by promoting cell growth in response to specific environmental cues. They can also influence root development, apical dominance, and tropic responses like phototropism and gravitropism. Auxins work by triggering changes in gene expression and protein activities within plant cells, ultimately leading to various growth responses.
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.
Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
What is the survival value of tactic response and tropic response?
Auxins
Auxins act in response to?
Auxin stimulates growth
What do Auxin's response to?
Auxins response to external stimuli like water, sunlight, support(thread), gravity etc.
What promotes fruit growth?
Auxins promote cytokinins, so they then work together to promote fruit growth while ethylene promotes fruit ripening.
What plant hormones promote stem growth and the development of fruits?
Auxins promote stem growth by stimulating cell elongation and differentiation. Cytokinins also play a role in stem growth by promoting cell division. Ethylene and auxins are involved in fruit development, with ethylene being particularly important in ripening fruit.
How do auxins relate to phototropism and gravitropism?
Auxins are plant hormones that play a key role in both phototropism (growth towards light) and gravitropism (growth in response to gravity). In phototropism, auxins accumulate on the shaded side of the stem, promoting cell elongation and bending towards the light source. In gravitropism, auxins redistribute in response to gravity, causing differential growth and either upward (negative gravitropism) or downward (positive gravitropism) bending of the stem.
What of the plant hormones influence parthenocarpy?
Auxins and gibberellins are plant hormones that can influence parthenocarpy, the production of fruit without fertilization. Auxins promote cell division and expansion, while gibberellins regulate fruit growth and development, both of which are important for parthenocarpy to occur.
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.
How does chemical coordination occur in plants?
Chemical coordination in plants is primarily regulated by plant hormones, which are signaling molecules that influence growth, development, and response to environmental stimuli. These hormones are produced in specific tissues and transported to target cells to elicit a response. The main plant hormones include auxins, cytokinins, gibberellins, abscisic acid, and ethylene.
How do auxin's control a plants response to light?
Auxins play a crucial role in phototropism, the plant's growth response to light. They promote elongation of cells on the shaded side of the plant, causing it to bend towards the light source.

What do auxins control in plants?
Auxins primarily control plant growth and development, including elongation of cells, root development, and tropic responses such as phototropism and gravitropism. They also play a role in apical dominance, lateral root formation, and fruit development.
Which of these plant hormones hastens the ripening of fruit and helps to cause the fall of leaves flowers and fruit a cytokinins b auxins c ethylene d gibberellins?
auxins are group of related chemical substances which activity greatly affect the physiological processses in plant and animal.auxins helps in stimulating plant growth and also hasten fruit ripening.
