Carpophore is a botanical term that refers to the stalk that supports a fruiting body in certain plants. Some synonyms for this word include stalk, peduncle, and receptacle. Stalk refers to a slender, vertical support structure that terminates in a bud, flower, or fruit. Peduncle, on the other hand, describes the main stem or stalk of an inflorescence or fruit cluster. As for receptacle, it is a structure that supports the floral organs and acts as a platform for the developing fruit. All of these words are important botanical terms that help describe the different parts of a plant.
