Members of this phylum of vascular, seed-bearing plants have the largest sperm known. Many look like palm trees, but they reproduce using cones (some have female cones as nearly as heavy as many adult humans). They were a dominant plant group in the Mesozoic era. A) Ginkgophyta (ginkgos) D) Cycadophyta (cycads) B) Anthophyta (flowering plants) E) Coniferophyta (conifers) C) Gnetophyta (gnetophytes) ____ 9. This phylum of vascular, seed-bearing plants has only about 70 living species in three genera, including Wel- witschia and Ephedra . They are the only gymnosperms with xylem containing vessels, a trait common in an- giosperms. A) Gnetophyta (gnetophytes) D) Coniferophyta (conifers) B) Pterophyta (ferns) E) Ginkgophyta (ginkgos) C) Cycadophyta (cycads) ____ 10. Members of this phylum have radial symmetry. Many are bioluminescent. Some use tentacles to capture prey. They have characteristic plates of fused cilia that they use for movement, making them the largest an- imals to use cilia as their primary means of locomotion. A)
