👉 Enneaphyllus is a type of leaf that has two layers of cells, with the inner layer being a thin, waxy layer called an enneaerythrum and the outer layer being a more dense layer called an enneaerythrin. This arrangement allows for efficient water absorption and transmission of light energy to the stroma of the cell. Enneaphyllus is often used in hydroponics as a source of nutrients, particularly essential vitamins and minerals.
