Phylloclades are modified stems or branches that perform the functions of leaves. Some synonyms for this term include cladodes, stem leaves, and flattened shoots. Cladodes are typically seen in succulent plants such as cacti and have a flattened, leaf-like appearance. Stem leaves are another term that refers to phylloclades, which can be found in plants that have adapted to dry or arid conditions. Flattened shoots are used to describe the modified stems that contain chlorophyll and perform photosynthesis in place of normal leaves. No matter what synonym is used, the phylloclade plays a crucial role in the survival and adaptation of certain plants to their environment.
