Chemical Coordination in Plants Welcome to your Chemical Coordination in Plants 1. Positive geotropism is exhibited by Stem Leaves Shoot Root2. A plant hormone for inducing Morphogenesis in plant tissue culture is Ethylene Gibberellin Cytokinin Abscisic acid3. To increase sugar production in sugarcanes, they are sprayed with Cytokinin IAA ABA Gibberellin4. Internodal elongation is associated with Cytokinin Gibberellin ABA Auxin5. Which of the following regulate closure of stomata? Auxins Bromic acid ABA Cytokinin6. Cell division in plants is promoted by ABA Cytokinin Ethylene Gibberellin7. Which of the following is not an effect of ethylene? Promotes senescence and abscission of plant organs Breaks seed and bud dormancy Hastens fruit ripening Helps to overcome apical dominance8. The phytohormone that helps in the germination of seeds is Auxin ABA Cytokinin Gibberellin9. The hormone responsible for phototropism and geotropism is Auxin Enzyme Gibberellin Starch10. Which one of the following pairs is not correctly matched? Gibberellic acid - Leaf fall Cytokinin - Cell division Abscisic acid - Stomatal closure IAA - Cell wall elongation11. The phytohormone that prevents the germination of seeds is Abscisic acid Cytokinin Auxin Gibberellin12. One of the synthetic auxin is GA NAA IAA IBA13. A plant hormone related with inhibition of senescence is Ethylene Bromic acid ABA Gibberellin14. A phytohormone existing in gaseous state is Cytokinin Abscisic acid Auxin Ethylene15. Ethylene is used for Both hastening of ripening of fruits and slowing down ripening of apples Slowing down ripening of apples Retarding ripening of tomatoes Hastening of ripening of fruits16 out of 15Please fill in the comment box below.
