An example of a plant that has a fibrous root system

• A. Carrots
• B. Pine tree
• C. Oak tree
• D. Lawn grasses

Answer: (D)

Fibrous roots are a network of many thin roots that spread out from the base of the plant, forming a dense, shallow system rather than one dominant root. This pattern is characteristically seen in grasses, so lawn grasses have a fibrous root system. Carrots rely on a single thick primary root that grows downward with smaller lateral roots—this is a taproot system, not fibrous. Pine trees start with a taproot and develop numerous lateral roots, but the overall architecture isn’t a dense mat of similarly sized roots near the surface. Oak trees also emphasize a strong primary root with expansive, deeper growth rather than a shallow, fibrous mat. So, the plant that exemplifies a fibrous root system is lawn grasses.
