Most ferns are small plants that lack woody tissue. In this lab you will investigate the diversity of pterophytes, including whisk fens, horsetails and a variety of ferns. The plants on display are sporophytes, the dominant generation in seedless vascular plants.Procedure: 1. Examine a living whisk fern on display. This is one of only two extant genera of Psilophytes. Observe the spherical structures on the stem.n this lab you will investigate the diversity of pterophytes, including whisk fens, horsetails and a variety of ferns.
