What is the main role of auxin?
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 are auxins explain their role in detail?
Auxins are a group of naturally occurring and artificially synthesised plant hormones. They play an important role in the regulation of plant growth. Auxins were initially isolated from human urine. Auxin means to “enlarge” or “increase”. They induce cell division, differentiation and elongation.

What is auxin What is its role in the growth of plants?
Auxins are a powerful growth hormone produced naturally by plants. They are found in shoot and root tips and promote cell division, stem and root growth. They can also drastically affect plant orientation by promoting cell division to one side of the plant in response to sunlight and gravity.May 5, 2016

What role does auxin play in plants Class 10?
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.
Which one is main role of auxin in plants Mcq?
They promote cell elongation, fruit development, root initiation from cuttings and are responsible for apical dominance and phototropism.
Which one is main role of auxin in plants?
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 one main effect of auxins on plant growth?
Auxins are a class of phytohormones that control numerous processes of plant growth and development (Davies, 2013). Auxins are known primarily for their ability to induce cell elongation. In addition, they stimulate cell division, vascular differentiation, and root initiation.Dec 8, 2020
What are the role of auxin in plants Class 11?
-Auxin promotes the development and root formation in the plants. It induces both the growth of the existing as well as lateral root branching. The high concentration of auxin inhibits root elongation and results in the adventitious root formation. -Auxin is known to induce shoot apical dominance.
Which of the following is a plant hormone Mcq?
So, the correct answer is 'Cytokinin'
