• E. 1- c, 2- b, 3- a, 4- e, 5- d

Answer 1

The correct option is A 1- b, 2- e, 3- a, 4- c, 5- d

Indole-3-acetic acid is an integral part of human urine and serum and urine is responsible for the auxin effect. Giberella fujikori is the fungus from which gibberellin hormone was first isolated. It was found as a result of the studies related to bakane disease, which is also known as foolish seedling disease. Herring sperm DNA has cell division promoting activity. It is thus related to the kinetin enzyme, which is responsible for the multiplication of cells. Spraying of ethylene causes the ripening of fruits. It is a phytohormone which is present in gaseous form. Abscisic acid is related to stomatal closure in water stress conditions. It also induces dormancy in plants during seed germination.

So, the correct answer is '1- b, 2- e, 3- a, 4- c, 5- d'
