What "taproot" means in gardening

A taproot is the main, central root of a plant that grows straight down into the soil, serving as the primary anchor for the plant and absorbing nutrients and water from deep in the soil. Many plants have taproots, including carrots, radishes, and dandelions, while others, like grasses, have fibrous root systems that do not include a taproot. A well-developed taproot can help a plant to survive drought and other adverse conditions by accessing moisture and nutrients from deeper soil layers.
