👉 Laciniation is a process in plants where the roots pierce and extend their root system through the soil surface to reach deeper into the ground. This process enables the plant to access nutrients, water, air, and other resources that are not available at the surface of the soil. The term "laciniation" was coined by botanist Charles Darwin in his book On the Origin of Species, where he described the process as a key feature of plants that enabled their survival on land.
