Which type of plants have hollow, rounded stems with closed and hard joints?

• A. Broadleaf plants
• B. Herbaceous perennials
• C. Nutsedges
• D. Annual grasses

Answer: (C)

The correct answer is that nutsedges are characterized by hollow, rounded stems with closed and hard joints. Nutsedges belong to the family Cyperaceae and are often mistaken for grasses; however, they have distinct morphological traits. The hollow stems of nutsedges give them a unique structure compared to many other types of plants. Nutsedges grow from tuberous root structures, which can contribute to their persistence in the landscape. The closed joints further distinguish them from many broadleaf plants and grasses, which typically have solid stems and varying stem structures. This anatomical characteristic is important for identifying nutsedges in turf management and ornamental settings, as they can be troublesome weeds in both ecosystems due to their rapid growth and resilience. Understanding the specific characteristics of nutsedges allows pest supervisors to implement effective management strategies and address their presence in ornamental and turf areas proficiently.
