In Barley Seed Germination, Which of the Following is True

Question

In barley seed germination, which of the following is true?
A) The aleurone cells determine when germination occurs by secreting α-amylase.
B) The aleurone cells determine when germination occurs by secreting gibberellin.
C) The embryo determines when germination occurs by secreting α-amylase.
D) The embryo determines when germination occurs by secreting abscisic acid.
E) The embryo determines when germination occurs by secreting gibberellin.

Accepted Answer

The embryo in barley seeds secretes gibberellin, which then signals the aleurone cells to produce enzymes like α-amylase necessary for breaking down starches during germination.
