Question

12. Be able to place the following characters on the land plant phylogenetic tree: heteromorphic alternation of generations, cuticle, pores, stomata, vascular tissue, seeds, pollen 13. Know each of the following terms so when I use them in sentences you know to what I am referring and what purpose it has: vascular tissue, embryophyte, tracheid, vessel element, cuticle, pore, stomata, pollen, ovule, seed, fruit, gymnosperm, angiosperm 14. Be able to identify which of those terms above apply to each of the following plant phyla. In other words, be able to tell me which characters apply to which groups and also be ready to mark the appropriate characters on a phylogenetic tree 15. For each phylum known common name and formal name E.g. Liverworts- Hepatophyta. You'll need to know Bryophyta, Hepatophyta, Monilophyta, Coniferophyta, Ginkgophyta, Cycadophyta, Gnetophyta, and Anthophyta 16. Be able to explain the structural and reproductive challenges that were associated with the movement from aquatic to terrestrial environments. How did different groups of plants survive in the face of terrestrial challenges? 17. Explain in detail the differences in the location of the male and female gametophytes in seed plants vs. non- seed plants. Why are pollen and seeds so important in the evolution of land plant lineages? 18. Compare and contrast gymnosperms and angiosperms with respect to the following: location of male and female gametophytes, location of ovule, presence or absence of fruit, food source for developing embryo

Explanation / Answer

15) Bryophyta = mosses; Hepatophyta = liverworts; Monilophyta = Horsetails and ferns; Coniferophta = conifers; Ginkgophyta = Ginkgi; Cycadophyta = Cycas and Zamia; Gnetophya = Gnetum, Ephedra; Anthophyta = Lily, sunflower

17) Male and female gametophyte in seed plants - The female gametophyte is present in pistil, located in the middle of the flower and the male gametophyte is present in pollen grain

Male and female gametophytes in seedless plants - Sperm are produced in the male gametangium, the antheridium and eggs are produced in the female gametangium, the archegonium

18) Angiosperm -

Gymnosperm -
