Solution for QID #20511: Chapter 26 worksheet 1)Compared to seedless plants, seed | StudyHelpMe

Chapter 26 worksheet 1)Compared to seedless plants, seed plants dominate the land and are found in diverse environments. What major adaptation is most likely the cause of this success? Explain. 2) Describe the evolutionary trends of the seed plant in terms of the sporophyte generation, the gametophyte, and spore production. 3) Differentiate between megaspores and microspores. 4) What two critical adaptations (evolutionary advantages) distinguish seed plants from seedless plants and allowed them to survive on dry land? Explain how these adaptations bypasses the need for water and allow for the success of seed plants. 5) What is an ovule? What is a pollen grain? 6. What is a seed? Describe the three major components and the benefits of each. 7. What defines a gymnosperm? What defines an angiosperm?  8. Based on fossil record, in what period did gymnosperm dominate? When did the angiosperm surpass the gymnosperm? Which are currently the most abundant plants? 9. Define flower. Define fruit. (Make sure to include the purpose.) What are the evolutionary advantages of these two structures? In what plant group(s) are they found? Section 26.2 10. Are gymnosperms monophyletic? Explain. 11. Define sporophyll. Give an example. 12. Define integument. 13. Differentiate between monoecious and dioecious plants. 14. Fill in the following chart: Division and common name, Defining characteristics + fossil records, Example(s) Flagellated sperm?, Monoecious?, Dioecious? Coniferophyta (conifers) Gingkophyta Cycadophyta Gnetophyta 15. Describe the life cycle of a pine tree Section 26.3 16. Draw a typical flower. Label the major parts (sepals, petals, carpel/pistil, stigma, style, ovary, filament stamen, anther, receptacle). Make sure to note the male and female reproductive structures and the purpose of each part. 17. Describe the life cycle of an angiosperm; make note of double fertilization and its two products. 18. What is a cotyledon? 19. Define a perfect flower. Is self-pollination common in perfect flowers? Explain. 20. Why are vegetables such as eggplants and string beans considered fruits? 21. Mature fruits can be classified in two ways. What are these? Give an example of each. 22. Not all fruits originate from just the ovary. From what floral part(s) are the following derived? (1) Strawberry: (2) Apple: (3) Raspberry: (4) Pineapple: 23. The ultimate purpose of fruits is ___________________________________________________. 24. Differentiate between monocots and dicots by filling in the following chart: Monocot Dicot (a.k.a. Eudicot) Number of cotyledon Venation (vein pattern) Floral parts Stem vascular arrangement Type of root (root system) Pollen shape Section 26.4 25. Describe the process of pollination and the role of pollinators.
