A photosynthetic branch or portion of a stem that functions as or resembles a leaf, as the pad of a prickly-pear cactus. Also called cladophyll.
Origin of cladodeNew Latin clad&omacron;dium, from Late Greek klad&omacron;d&emacron;s, many-branched, from Greek klados, branch.
- (botany) A flattened organ arising from the stem of a plant. These often replace the leaves in photosynthetic function, as leaves in such plants (for example asparagus, butchers broom) are typically reduced to scales. May also refer to the generally flattened shoot such as the cactus shown.
