What is auxin and its function class 10?
Auxins are growth hormones produced by plants. They are essential for proper growth of the plant and cell elongation. They also regulate phototropism, geotropism, and hydrotropism in plants.
What is auxin and its function?
Auxin is a key regulator of plant growth and development, orchestrating cell division, elongation and differentiation, embryonic development, root and stem tropisms, apical dominance, and transition to flowering.Jul 23, 2014

What is the function of auxin class 10th?
It helps in cell differentiation and regeneration of vascular tissues (phloem, xylem). Callus Formation and Morphogenesis: Auxin along with cytokinin induces callus formation in explant and stimulates morphogenesis. Secondary Growth: Auxin promotes secondary growth and induces cell division in the vascular cambium.

What are plant hormones Class 10 which chapter?
Answer : Plant hormones(also known as phytohormones) are the chemical substances which help in controlling growth, flowering, height, development of plants and their response to the environment. Various types of phytohormones are – auxins, gibberellins, cytokinins, abscisic acid and ethylene.

Auxin and gibberellins are the two plant growth hormones.
What are the three function of auxin?
Functions: Cell elongation of stems and roots. Apical dominance, IAA in apical bud suppresses the growth of lateral buds. Induces parthenocarpy i.e. development of fruit without fertilisation e.g. in tomatoes.May 20, 2022
