Illustration of the walnut seed (edible kernel) showing two convoluted cotyledons separated by a central groove. In botanical hierarchy, this seed resides within the woody endocarp of the walnut fruit (a drupe) on a Juglans tree. In plant anatomy and seed physiology, the cotyledons function as nutrient storage tissue, rich in lipids that fuel embryo germination and serve as a human food source. The entity depicted is a plant reproductive structure with lobulated surfaces and deep sulci characteristic of walnut kernels.
