Final answer:
The question seems to be based on a typographical error, as Fitzpatrick types refer to human skin classification. However, in the context of plant root systems, a deep taproot system allows plants to access deeper soil moisture, while a shallow fibrous root system helps in water absorption from light rainfall and provides anchorage to prevent soil erosion.
Step-by-step explanation:
The Fitzpatrick types being mentioned seem like a typographical error, as they usually refer to human skin classification and are not relevant to root systems in plants. However, we can discuss the different root systems that plants may have, especially in relation to dry environments such as deserts. Taproot and fibrous root systems are the two main types of root systems in plants.
A deep taproot system, often found in dicots like dandelions, consists of a main root that grows down vertically with lateral roots sprouting from it. This system allows plants to access deeper soil regions that retain moisture even after several rainfalls, providing a stable water supply during drought conditions; an example being the deep roots of desert plants that can extend up to 20-30 feet underground.
Conversely, a shallow fibrous system, characteristic of monocots such as lawn grasses, wheat, rice, and corn, consists of a dense network of roots near the soil surface. This type of root system provides anchorage and increases the amount of water absorbed from light rainfalls, when the topsoil dries quickly. It also helps in preventing soil erosion due to its wide coverage.
