Beer breweries use gibberellins to ensure consistent germination and liberation of sugars from starch in grain endosperm.Which layer of the grain responds to the applied gibberellins?
A) Mesophyll
B) Cotyledon
C) Aleurone
D) Seed coat
E) Embryo

Question

Quizplus · Accepted Answer

The aleurone layer is the outermost layer of the endosperm in cereal grains such as barley and wheat. It is responsible for the production of digestive enzymes such as amylases that break down starch into fermentable sugars during the malting process. Gibberellins applied to the grains induce the aleurone layer to produce more amylases, ensuring consistent germination and sugar extraction.
