Chemical Coordination in Plants Welcome to your Chemical Coordination in Plants 1. One of the synthetic auxin is GA IBA IAA NAA2. The hormone responsible for phototropism and geotropism is Gibberellin Auxin Starch Enzyme3. Cell division in plants is promoted by ABA Cytokinin Gibberellin Ethylene4. A plant hormone for inducing Morphogenesis in plant tissue culture is Ethylene Gibberellin Cytokinin Abscisic acid5. Ethylene is used for Retarding ripening of tomatoes Slowing down ripening of apples Both hastening of ripening of fruits and slowing down ripening of apples Hastening of ripening of fruits6. Which of the following is not an effect of ethylene? Promotes senescence and abscission of plant organs Helps to overcome apical dominance Breaks seed and bud dormancy Hastens fruit ripening7. A phytohormone existing in gaseous state is Auxin Cytokinin Abscisic acid Ethylene8. A plant hormone related with inhibition of senescence is Bromic acid Gibberellin Ethylene ABA9. Internodal elongation is associated with Cytokinin ABA Gibberellin Auxin10. The phytohormone that helps in the germination of seeds is ABA Cytokinin Auxin Gibberellin11. To increase sugar production in sugarcanes, they are sprayed with IAA Gibberellin ABA Cytokinin12. Which of the following regulate closure of stomata? Cytokinin Auxins ABA Bromic acid13. Positive geotropism is exhibited by Shoot Root Leaves Stem14. Which one of the following pairs is not correctly matched? Cytokinin - Cell division Abscisic acid - Stomatal closure IAA - Cell wall elongation Gibberellic acid - Leaf fall15. The phytohormone that prevents the germination of seeds is Cytokinin Auxin Abscisic acid Gibberellin16 out of 15Please fill in the comment box below.
