What is the function of the ligule in grasses?

• A. Reproduction
• B. Nutrient transport
• C. Protection
• D. Water uptake

Answer: (C)

The ligule in grasses serves a protective function at the junction of the leaf blade and sheath. It plays a crucial role in preventing water loss and protecting the plant from pests and pathogens. The ligule's structure can vary among grass species, but it generally helps to seal the gap where the leaf joins the stem, minimizing the potential entry point for harmful organisms. Additionally, it assists in maintaining the plant's overall integrity by preventing desiccation and physical damage. Understanding the role of the ligule is essential for recognizing how grasses adapt to their environments and protect themselves, thereby contributing to their survival and growth.
