Chemical Coordination in Plants Welcome to your Chemical Coordination in Plants 1. To increase sugar production in sugarcanes, they are sprayed with Cytokinin Gibberellin IAA ABA2. Internodal elongation is associated with ABA Auxin Cytokinin Gibberellin3. A plant hormone for inducing Morphogenesis in plant tissue culture is Ethylene Gibberellin Abscisic acid Cytokinin4. One of the synthetic auxin is IAA GA NAA IBA5. Ethylene is used for Slowing down ripening of apples Hastening of ripening of fruits Both hastening of ripening of fruits and slowing down ripening of apples Retarding ripening of tomatoes6. The hormone responsible for phototropism and geotropism is Starch Auxin Enzyme Gibberellin7. The phytohormone that prevents the germination of seeds is Cytokinin Gibberellin Auxin Abscisic acid8. Cell division in plants is promoted by ABA Cytokinin Ethylene Gibberellin9. Which of the following is not an effect of ethylene? Breaks seed and bud dormancy Promotes senescence and abscission of plant organs Helps to overcome apical dominance Hastens fruit ripening10. The phytohormone that helps in the germination of seeds is ABA Auxin Cytokinin Gibberellin11. A phytohormone existing in gaseous state is Ethylene Auxin Cytokinin Abscisic acid12. Positive geotropism is exhibited by Shoot Root Stem Leaves13. Which of the following regulate closure of stomata? Bromic acid Auxins Cytokinin ABA14. A plant hormone related with inhibition of senescence is Ethylene Bromic acid Gibberellin ABA15. Which one of the following pairs is not correctly matched? Gibberellic acid - Leaf fall Cytokinin - Cell division Abscisic acid - Stomatal closure IAA - Cell wall elongation16 out of 15Please fill in the comment box below.
