Figure It Out: Which of the plants shown here are in the same order?Linnean- or rank based classification systems have placed the cycads, ginkgo, conifers and gnetophytes, respectively, into separate categories, of equal ranking (i.e., each gymnosperm group a Phylum or Division). Is the Linnaean classification of each gymnosperm group justifiable, based on the information shown in the figures?
