Final answer:
A taproot system is characterized by a single large root with smaller branch roots, whereas a fibrous root system is characterized by many smaller roots of similar diameter. Fibrous root systems are found in monocots and taproot systems are found in dicots.
Step-by-step explanation:
A taproot system is characterized by a single large root with smaller branch roots, whereas a fibrous root system is characterized by many smaller roots of similar diameter. Fibrous root systems are found in monocots, such as grasses, wheat, rice, and corn, and they are located closer to the soil surface. On the other hand, taproot systems are found in dicots, like carrots, and they have a single main root that grows down vertically with lateral roots branching out from it.
