Explanation:

Seed coats are one of three parts of a plant seed, in addition to the endosperm and the embryo. The endosperm is the food storage area of the seed. The purpose of the seed coat is to protect the seed from physical, temperature-related, or water damage.

*functions*

The number one function of a seed coat is similar to that of the protective gear worn by people in high-risk lines of work: to make sure the seed doesn't come to any harm. What kind of harm do seeds encounter? Well, seeds can be damaged when planting from crushing or insertion into the ground. They can also be hurt during insect or microbial attacks after planting or during storage.

A seed also needs protection from water, heat, and freezing that can affect its ability to mature into a plant. For example, the seed coat keeps too much water from reaching the internal seed structures, as well as prevents these structures from drying out. The seed coat also provides a degree of insulation and protection from sub-freezing temperatures. In addition, the very thick seed coats found on a lot of tree nuts keep the seed from burning during a fire.
