Some seeds require darkness to germinate because they are adapted to grow in shaded environments, such as under the soil or beneath other plants. In the dark, these seeds can sprout and grow without the risk of being exposed to harsh sunlight. The darkness helps trigger the germination process, allowing the seed to use its stored energy to grow roots and stems before reaching the surface. This is an important adaptation for seeds that grow in places where sunlight is limited.
