Lateral roots are secondary roots that grow out from the main root of a plant. They help anchor the plant in the soil and increase its ability to absorb water and nutrients. These roots develop from the pericycle, a layer of cells located just inside the main root's outer layer. The formation of lateral roots is essential for a plant's stability and overall health. By expanding the root system, lateral roots allow plants to access a larger volume of soil, which is crucial for their growth and survival. This process is influenced by various factors, including soil conditions and the presence of water.
