Seed Coat

Imagine going outside on a windy day without a jacket, and feeling the chill instantly. Just like a jacket protects you from harsh weather, the seed coat acts as a tough outer layer that shields the plant embryo from the drying effects of the environment. Both the jacket and the seed coat serve as protective barriers, ensuring that what's inside stays safe and retains its necessary conditions, whether that's your body heat or the moisture essential for the plant embryo's survival.
