Endocarp

The endocarp is the innermost layer of the pericarp, the fruit wall, which surrounds the seeds in flowering plants. It is the tissue layer immediately adjacent to the seeds and can vary significantly in texture, thickness, and composition depending on the fruit type. The endocarp's primary function is to protect and potentially nourish the seeds as they develop. It can be fleshy, forming the edible portion of fruits like peaches and plums, or it can be tough and stony, as found in the pits of drupes like cherries and olives. Its structure plays a vital role in seed dispersal, either aiding in the consumption and distribution of seeds, or physically protecting them until the optimal germination conditions arise. Understanding endocarp characteristics is crucial for fruit identification and classification.
