Sporangiophores are specialized structures in certain fungi and plants that bear sporangia, which are containers for spores. In fungi, they often emerge from mycelium and can be involved in the asexual reproduction process. In vascular plants, sporangiophores may be found in structures like strobili or cones, where they play a role in the production of spores for reproduction. Overall, they are crucial for the dispersal and propagation of the organism.
