The photo below illustrates an unusual difference between the Pteridophytes and the Equisetales. Which answer below best represents this unusual difference? a Equisetales have a separate vegetative and fertile shoots Equisetales are gametophyte dominant Equisetales don't produce spores Equisetale sporophytes are nutritionally dependent upon the gametophyte phase MacBooMatch the following taxa and descriptions to their corresponding and appropriate group or classification.
