What is the lower part of a grass leaf called?

The lower part of a grass leaf is referred to as the sheath. The sheath is the part of the leaf that wraps around the stem of the plant, securing the leaf in place and helping to protect the stem from potential damage and dehydration. It plays an important role in the overall structure of the grass, providing support and stability.

In contrast, the blade of the leaf is the wide, flat part that is typically responsible for photosynthesis. The blade captures sunlight and allows the plant to produce energy. The shaft tends to suggest a more elongated part of the structure in other types of plants but is not a term specifically used in the context of grass leaves.

The base of a leaf refers to the point where the leaf attaches to the stem or sheath. Understanding these different parts is essential for recognizing how grass and similar plants grow and develop, as well as how to manage them effectively in various applications such as landscaping and turf management.
