Explanation

The function of the ligule is multifaceted and can include the following:

Hygroscopic function: The ligule can be hygroscopic, meaning that it can absorb or release moisture depending on environmental conditions, helping to keep the plant's surface dry.

Perennation: The ligule can act as a protective layer over the dormant buds of the plant, helping it to survive through the winter or other periods of dormancy.

Reproduction: In some plants, the ligule can play a role in reproduction by producing flowers or facilitating pollination.
