The seed contains and disperses the embryo. Around the whole seed is a layer called the seed coat. This layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals.When conditions are right -- there is appropriate light and water -- the seed coat may trigger the germination of the seed.his layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals. When conditions are right -- there is appropriate light and water -- the seed coat may trigger the germination of the seed.
If the seed lands where the conditions are right, the embryo germinates and grows into a new plant. Scientists divide seed plants into two main groups: plants with flowers and plants with cones. They also have special names for these groups. Plants that have flowers are called angiosperms. Plants that hold their seeds in cones are called gymnosperms. Angiosperms â seed plants with flowers. Angiosperms have flowers.
