Answer:
All of these
Step-by-step explanation:
Seed dormancy and germination are regulated by several plant hormones, such as abscisic acid, gibberellin, auxin (indole-3-acetic acid), ethylene, and brassinosteroid.
When germination starts seeds absorb water and produce various enzymes that help in breakdown of the reserve food into simpler molecules.
α-amylase and β-amylase are involved in degradation of endosperm starch.
most seeds are rich in: protein, healthy fats (higher proportion of polyunsaturated fats) and fibre. minerals (such as magnesium, potassium, calcium, plant iron and zinc), vitamins B1, B2, B3 and vitamin E.
