A large, central root that grows straight down from a plant's stem, with smaller lateral roots branching off from it. This root system is typical of dicot plants and serves as both an anchor and storage organ.
From 'tap' (to strike or pierce) and 'root,' literally meaning 'piercing root.' The term emerged in the 17th century, describing how these roots seem to tap or bore straight down into the earth like a drill.
Taproots are nature's drilling equipment, with some desert plants like mesquite sending roots down over 175 feet to reach groundwater! This incredible depth allows them to access water sources that shallow-rooted plants can't reach, making them champion drought survivors.
