An enzyme that can stimulate germination of barley seeds is
α-amylase
lipase
protease
protease
A.
α-amylase
Barely seeds are rich in carbohydrate (Starch). The starch is hydrolysed by α-amylase to monosaccharides unit at the time of germination of seeds.
A dioecious flowering plant prevents both:
Autogamy and xenogamy
Autogamy and geitonogamy
Geitonogamy and xenogamy
Geitonogamy and xenogamy
B.
Autogamy and geitonogamy
In a cereal grain the single cotyledon of embryo is represented by
coleorhiza
scutellum
prophyll
prophyll
A.
coleorhiza
In a cereal grain (e.g., wheat), the single cotyledon of embryo is represented by the scutellum. Scutellum is specialized for nutrient absorption from the endosperm.
Coleoptile is a modified ensheathing leaf that covers and protects the young primary leaves of a grass seedling.
Coleorhiza is a sheath-like structure found on the radicle which covers and protects it during the growth into the soil.
