Plant Root System Diagram - Soil Penetration and Structure #3017374 (License: Personal Use)

This vintage-style line drawing depicts a vertical cross-section of soil with a prominent taproot descending vertically, thickening near the base, and giving rise to several lateral roots that curve horizontally. The soil is rendered with diagonal hatching, indicating stratification, while the root structure is shaded to emphasize depth and morphology. The surface shows slight topsoil undulation, suggesting natural terrain.
