Vedclass · Answer

(C) In Pteridophytes,the main plant body is a sporophyte,which is differentiated into true root,stem,and leaves. These organs possess sporangia that are subtended by leaf-like appendages called sporophylls. In some cases,sporophylls may form distinct compact structures called strobili or cones. The sporangia produce spores by meiosis in spore mother cells. Since the sporophyte produces spores,it is responsible for spore formation,which is a key part of the asexual phase of their life cycle. Therefore,both $(A)$ and $(B)$ are correct.

In Pteridophytes,the main plant body is responsible for which of the following?
