Question

Which of the following statements is correct?

• A. Pteridophytes have both microphylls and macrophylls
• B. Sporophylls form compact structures called strobili
• C. Sporangia are present on sporophytes
• D. Sporangia produce spores by mitosis in spore mother cells

Answer 1

Answer: (A), (B), (C)

The correct options are
A Pteridophytes have both microphylls and macrophylls
B Sporophylls form compact structures called strobili
C Sporangia are present on sporophytes

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). The sporangia produce spores by meiosis in spore mother cells.
