What are the four effect of auxins in plant?
Auxins regulate numerous developmental processes in plants including cell expansion, root initiation, vascular tissue differentiation, bud and flower growth (Davies, 2013).Dec 8, 2020
Which of the following are auxin effects in plants?
Auxin is an important plant hormone which has direct effect on cell elongation, multiplication, phototactic movements, etc. It is found commercially helpful because of several characters like: callus formation, curvature of stem and induction of growth of root in stem cuttings.
Which of the following is the function 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

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 of the following is a plant auxin?
Indole-3-acetic acid is the most common naturally occurring plant hormone of the auxin class.
Which of the following is plant auxin?
Indole-3-acetic acid is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins and has been the subject of extensive studies by plant physiologists.
What is an example of auxin?
Five naturally occurring (endogenous) auxins in plants include indole-3-acetic acid, 4-chloroindole-3-acetic acid, phenylacetic acid, indole-3-butyric acid, and indole-3-propionic acid.
Which of the following is an example of auxin?
Indole-3-acetic acid (IAA) is the most abundant and the basic auxin natively occurring and functioning in plants. It generates the majority of auxin effects in intact plants, and is the most potent native auxin.
Which of the following are auxins?
So, the correct answer is ' IAA, IBA, NAA'.
Which is not an example of auxins?
So, the correct answer is 'indoleacetic acid (IAA) '.
