What is the primary purpose of a seed coat?

Explanation:
Seeds face many dangers while waiting to sprout, so the outer seed coat acts as a tough protective armor around the embryo inside. It helps shield the seed from drying out, physical damage, and disease. The coat also plays a big role in dispersal, with textures, shapes, or coatings that help seeds hitch rides on animals, catch the wind, or float away to new places, increasing the chances of growing somewhere new. While some coats can influence when a seed starts to germinate, the primary job is protection and helping seeds move to better locations. It isn’t about attracting pollinators or soaking up nutrients from soil—the former is the job of flowers, and nutrients are taken up after germination by the growing plant.
