The Seed Coat's Most Important Function is to Provide

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 to provide desiccation resistance, protecting the embryo from dehydration during seed development and after dispersal. While the seed coat may also assist in dispersal and provide some nutrient supply, these functions are not as fundamental as desiccation resistance. The seed coat does not directly contribute to the growth and development of the megasporangium, nor is it primarily responsible for dormancy, which is regulated by internal mechanisms within the seed.
