Chemical Coordination in Plants Welcome to your Chemical Coordination in Plants 1. Which of the following is not an effect of ethylene? Breaks seed and bud dormancy Hastens fruit ripening Promotes senescence and abscission of plant organs Helps to overcome apical dominance2. The hormone responsible for phototropism and geotropism is Starch Enzyme Auxin Gibberellin3. 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 fruits4. One of the synthetic auxin is NAA IBA IAA GA5. To increase sugar production in sugarcanes, they are sprayed with Cytokinin IAA ABA Gibberellin6. Which one of the following pairs is not correctly matched? Abscisic acid - Stomatal closure IAA - Cell wall elongation Gibberellic acid - Leaf fall Cytokinin - Cell division7. Positive geotropism is exhibited by Root Stem Shoot Leaves8. A plant hormone related with inhibition of senescence is Bromic acid ABA Ethylene Gibberellin9. A phytohormone existing in gaseous state is Ethylene Auxin Cytokinin Abscisic acid10. The phytohormone that helps in the germination of seeds is Cytokinin Gibberellin ABA Auxin11. Internodal elongation is associated with Gibberellin Cytokinin ABA Auxin12. A plant hormone for inducing Morphogenesis in plant tissue culture is Cytokinin Gibberellin Ethylene Abscisic acid13. Which of the following regulate closure of stomata? ABA Bromic acid Cytokinin Auxins14. The phytohormone that prevents the germination of seeds is Auxin Cytokinin Abscisic acid Gibberellin15. Cell division in plants is promoted by ABA Cytokinin Gibberellin Ethylene16 out of 15Please fill in the comment box below.
