👉 The term "malpighian" is a Greek word meaning "lower part," referring to the area within a root that is less developed, more primitive or lesser in complexity. It can also refer to the process of differentiation or differentiation between two or more parts or elements. In this context, it suggests the lower or subterranean parts of plants and animals, which are often found in soil, roots, and other structures where they have not yet undergone a significant transformation from their parent species.
