The sporophylls forms a distinct compact structures called ________ .

Step-by-step solution

The sporophytes bear sporangia that are subtended by leaf-like appendages called sporophylls. In some cases, sporophylls may form distinct compact structures called strobili or cones, especially in Selaginella, Equisetum . The sporangia produce spores by meiosis in spore mother cells. The spores germinate to give rise to the inconspicuous, small but multicellular prothallus.
