D3.1.12—Seed dispersal and germination question 1
[Maximum number: 5]
Outline the metabolic processes during germination of a starchy seed.
water must be absorbed by the seed (to become metabolically active); gibberellin is produced (in the embryo); stimulates production of amylase; which catalyses digestion of starch to maltose; maltose diffuses to the growing embryo root and shoot/growth regions; maltose is converted to glucose for (aerobic) cell respiration (to release energy); or to synthesize materials/cellulose for plant growth; Award the above to a clearly drawn correctly annotated diagram.
