The aleurone layer secretes some hydrolytic enzymes which cause breakdown of starch and protein. Their secretion is stimulated by(a) cytokinin ‘zeatin’, released in endosperm(b) triple fusion instigates the secretion of these enzymes(c) gibberellins, released by the embryo(d) embryo scutellum

Answer»

Answer is : (c) gibberellins, released by the embryo

Aleurone layer secretes amylase and protease enzyme which cause breakdown of starch and protein to simpler substances to be utilised during germination. Gibberellins released by embryo stimulate amylase and protease secretion at aleurone layer.
