Cladophyll, commonly known as a flattened stem, is a unique feature in some plants that can perform photosynthesis. Some synonyms for cladophyll include phylloclade, cladode, and cladomegaphyll. These terms are commonly used to describe a modified stem that has taken on the functions of a leaf to capture sunlight for photosynthesis. This adaptation is common in desert and arid regions where plants require a high degree of water-efficiency. The structure of the phylloclade varies, from thin, flattened needles to broad, leaf-like structures, depending on the species. In this way, the cladophyll presents a fascinating example of plant diversity and adaptation to changing conditions.
