Which statement about vernation is accurate?

Explanation:
Vernation describes how a grass leaf unfolds as it emerges from the sheath, and it can be folded or rolled. Bermudagrass emerges with the leaf folded, so it has folded vernation. Zoysiagrass, on the other hand, emerges with the leaf rolled, so it has rolled vernation. This difference helps distinguish the two grasses in the field because the way the leaf unfurls is a recognizable trait. If both had the same vernation, this diagnostic cue wouldn’t separate them, but the observed pattern—folded for bermudagrass and rolled for zoysiagrass—matches how these species appear in practice.
