The flat part of a leaf in grass plants is referred to as the blade. The blade is typically the most prominent and visible part of the grass leaf and is responsible for photosynthesis, which is the process by which plants convert light energy into chemical energy. The blade's shape and size can vary between different grass species, but it generally serves to maximize light capture.

The other terms have distinct meanings: the collar is the region where the blade meets the sheath and can often help identify grass species; the sheath is the part of the leaf that wraps around the stem; and the node is the point on the stem where leaves are attached, which is crucial for the growth and branching of the plant. Understanding these different parts is essential for agronomy studies, particularly in identifying and managing various grass species.
