plumule
Baby plant's sprout
A plumule is the embryonic shoot of a germinating seed—the part that develops into the stem and leaves.
In botany, it sits between the cotyledons (seed leaves) and pushes upward toward light as the plant emerges.
The term also refers to a small, soft feather, especially the downy type found beneath a bird's contour feathers.
