Question
What is the general structure of Pteridophytes?
✓
Answer
The main plant body is a sporophyte which is differentiated into true root, stem and leaves. These organs possess well-differentiated vascular tissues.
The leaves in pteridophyta are small (microphylls) as in Selaginella or large (macrophylls) as in ferns.
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 (Selaginella, Equisetum).
