Column I Column II
(A) Auxin (a) Promotes ripening of fruits
(B) Abscisic acid (b) Initiates cell division in tissue culture
(C) Cytokinin (c) Responsible for geotropic responses in roots
(D) Ethylene (d) Counteracts the effects of auxins
(E) Gibberellin (e) Promotes onset of dormancy
  (f) High concentration stimulates ethylene production
  (g) Stem elongation and leaf expansion


$\begin{array}{1 1}(A)\;A-(f),B-(c),C-(b),D-(a),E-(g)\\(B)\;A-(c),B-(f),C-(a),D-(b),E-(g)\\(C)\;A-(b),B-(a),C-(d),D-(g),E-(c)\\(D)\;A-(b),B-(a),C-(f),D-(a),E-(e)\end{array} $

1 Answer

Auxin-High concentration stimulates ethylene production
Abscisic acid-Responsible for geotropic responses in roots
Cytokinin-Initiates cell division in tissue culture
Ethylene-Promotes ripening of fruits
Gibberellin-Stem elongation and leaf expansion
