Question

The seed coat's most important function is to provide
A)a nonstressful environment for the megasporangium.
B)the means for dispersal.
C)dormancy.
D)a nutrient supply for the embryo.
E)desiccation resistance.

Accepted Answer

The seed coat's most important function is desiccation resistance, which protects the embryo from drying out as it waits for the right conditions to germinate. While the seed coat also plays a role in dispersal and dormancy, its primary function is to maintain the viability of the embryo. It does not provide a nutrient supply for the embryo, as this is typically stored in the endosperm or cotyledon.
