Zorluk: KolayPlant Science and Agricultural Technology

Plant growth regulators play a crucial role in agricultural practices and plant development. Which of the following plant hormones is primarily responsible for promoting fruit ripening?

  1. EthyleneCevap
  2. B
    Auxin
  3. C
    Gibberellin
  4. D
    Abscisic Acid

Cevap

Ethylene is the plant hormone primarily responsible for promoting fruit ripening.
Ethylene is a hydrocarbon gas acting as a natural plant hormone that accelerates cellular respiration, starch-to-sugar conversion, and tissue softening associated with fruit ripening.

Adım Adım Çözüm

1
Identify the primary physiological function required by the question.
The requirement is to identify the hormone responsible for fruit ripening.
Different plant hormones regulate distinct physiological and developmental processes.
2
Evaluate the functions of major plant hormones.
Ethylene functions as a gaseous regulator that hastens respiration and fruit ripening (climacteric ripening). Auxins handle tropisms and apical dominance, gibberellins promote seed germination and stem growth, and abscisic acid mediates stress responses and dormancy.
Matching each hormone to its primary role distinguishes ripening regulators from growth or stress regulators.
