👉 Juglandin is a type of protein found in plants and algae, particularly in their seeds. It plays a crucial role in plant growth by providing essential nutrients to the plant cells that are otherwise unavailable. The process of seedling development involves the initial formation of a seed cap and subsequent maturation into a fully-formed seed. This process requires the presence of juglandin for its function as an essential nutrient, which is crucial for the survival and health of the developing seedlings.
