Chemical Coordination in Plants Welcome to your Chemical Coordination in Plants 1. The phytohormone that helps in the germination of seeds is Gibberellin Auxin ABA Cytokinin2. Which one of the following pairs is not correctly matched? Abscisic acid - Stomatal closure IAA - Cell wall elongation Gibberellic acid - Leaf fall Cytokinin - Cell division3. Which of the following is not an effect of ethylene? Helps to overcome apical dominance Breaks seed and bud dormancy Promotes senescence and abscission of plant organs Hastens fruit ripening4. Positive geotropism is exhibited by Shoot Root Stem Leaves5. A plant hormone for inducing Morphogenesis in plant tissue culture is Abscisic acid Gibberellin Cytokinin Ethylene6. Ethylene is used for Retarding ripening of tomatoes Slowing down ripening of apples Hastening of ripening of fruits Both hastening of ripening of fruits and slowing down ripening of apples7. To increase sugar production in sugarcanes, they are sprayed with Gibberellin IAA Cytokinin ABA8. A plant hormone related with inhibition of senescence is ABA Bromic acid Ethylene Gibberellin9. One of the synthetic auxin is IAA GA NAA IBA10. The hormone responsible for phototropism and geotropism is Auxin Starch Enzyme Gibberellin11. Cell division in plants is promoted by ABA Cytokinin Ethylene Gibberellin12. Internodal elongation is associated with ABA Gibberellin Auxin Cytokinin13. Which of the following regulate closure of stomata? Bromic acid Cytokinin ABA Auxins14. A phytohormone existing in gaseous state is Abscisic acid Auxin Cytokinin Ethylene15. The phytohormone that prevents the germination of seeds is Gibberellin Cytokinin Auxin Abscisic acid16 out of 15Please fill in the comment box below.
