• A. Analogous organ
• B. Homologous organ
• C. Either homologous or analogous organ
• D. Modified stern

Answer 1

Answer: (A)

Analogous organ

Phyllodes and cladodes are examples of an analogous organ as both perform the function of photosynthesis and are different in origin. Cladode is modified green stem of limited growth which appears like leaves with spiny tips, e.g., Ruscus aceileuius, Asparagus. They may appear in the cluster or singly in the axil of scale leaf; while phyllode is the modified leaf (Petiole), it is aerial or branch modification, bearing nodes and internodes at intervals e.g., Opuntia.

Hence, the correct answer is option A.
