In grasses, the blade is the upper part of the leaf separated from the sheath by the collar and the ligule. Which part is the blade?

Explanation:
The blade is the upper, flat, photosynthetic portion of the leaf. It extends away from the stem and is separated from the sheath at the collar by the ligule. The sheath is the lower, wrapping part around the stem, and the ligule is the small membrane at the blade–sheath junction. So the blade is the upper part of the leaf.
