Chemical Coordination in Plants Welcome to your Chemical Coordination in Plants 1. A phytohormone existing in gaseous state is Cytokinin Ethylene Abscisic acid Auxin2. The phytohormone that helps in the germination of seeds is Cytokinin Gibberellin Auxin ABA3. Which of the following regulate closure of stomata? Bromic acid Auxins Cytokinin ABA4. To increase sugar production in sugarcanes, they are sprayed with IAA Gibberellin ABA Cytokinin5. Ethylene is used for Both hastening of ripening of fruits and slowing down ripening of apples Hastening of ripening of fruits Retarding ripening of tomatoes Slowing down ripening of apples6. Internodal elongation is associated with Gibberellin Auxin Cytokinin ABA7. Cell division in plants is promoted by ABA Ethylene Gibberellin Cytokinin8. The phytohormone that prevents the germination of seeds is Cytokinin Abscisic acid Gibberellin Auxin9. Positive geotropism is exhibited by Stem Leaves Root Shoot10. Which one of the following pairs is not correctly matched? Abscisic acid - Stomatal closure Cytokinin - Cell division IAA - Cell wall elongation Gibberellic acid - Leaf fall11. A plant hormone for inducing Morphogenesis in plant tissue culture is Ethylene Abscisic acid Cytokinin Gibberellin12. The hormone responsible for phototropism and geotropism is Auxin Gibberellin Enzyme Starch13. Which of the following is not an effect of ethylene? Helps to overcome apical dominance Breaks seed and bud dormancy Hastens fruit ripening Promotes senescence and abscission of plant organs14. One of the synthetic auxin is IAA GA IBA NAA15. A plant hormone related with inhibition of senescence is ABA Ethylene Bromic acid Gibberellin16 out of 15Please fill in the comment box below.
