Answer to Question #110553 in Cell Biology for Praise Onoyemeakpo

Question

A few years ago, the labels from one class section's experimental treatments plants fell off in the greenhouse and got swept away! One group was the only group in the section to test the effects of indole acetic acid (IAA) on bean plants. Other groups applied GA to their bean plants. The IAA group applied lanolin paste to one side of their bean stems. What should they for in order to identify their experimental plants from other groups?

Answer 1

IAA is the main auxin in plants, regulating growth and developmental processes such as cell division and elongation, tissue differentiation, apical dominance, and responses to light, gravity, and pathogens. Roots are most sensitive to fluctuations in IAA level.Lanolin is soft fat prepared form wool and is a good solvent for growth regulators. The paste is prepared with the fat and the growth regulator in a suitable preparation, sticks firmly and growth regulator does not dry out and remain in constant contact with the treated organ.Gibberellins are involved in the natural process of breaking dormancy and other aspects of germination. Gibberellins are produced in greater mass when the plant is exposed to cold temperatures. They stimulate cell elongation, breaking and budding, seedless fruits, and seed germination.

In this way the IAA,GA and lanolin works in beans plant.
