Which root system is commonly found in grasses and many lawn species?

• A. Fibrous
• B. Tap
• C. Adventitious
• D. Propagative

Answer: (A)

Grasses and lawn species form a fibrous root system, which is made up of many thin roots that grow outward from the crown and branch repeatedly. This creates a dense, shallow network that quickly takes up water and nutrients from the topsoil and helps stabilize the turf. A tap root, by contrast, is a single thick primary root with smaller side roots, which is common in many dicot plants. Adventitious roots can arise from stems or other non-root tissues, but the defining feature for grasses remains the many fine roots forming a fibrous system. Propagative describes how a plant spreads, not its root structure. So the fibrous root system best describes grasses and lawn species.
