Enriched Biology Study Guide
Plants: Chapters 30-33
Unit Objectives
By the end of this unit, you should be able to…
1) List the four major groups of plants and identify and describe the evolutionary milestones that developed in each group.
2) Summarize the concept of alternation of generations and apply it to describing reproduction in all the major plant groups.
3) Compare and contrast reproduction in bryophytes, ferns and fern allies, gymnosperms, and angiosperms.
4) Summarize the major trends in plant reproduction that evolved from bryophytes to angiosperms, including the relative dominance of the gametophyte and sporophyte generations and the dependence of each group on water.
5) Identify the major parts of a flower and state their functions
6) Summarize the process of seed germination, including the role of abscisic acid.
7) Explain the role of fruits in angiosperm reproduction, list several examples of fruits, and explain the role of ethylene in fruit ripening.
8) Compare and contrast monocots and dicots in terms of flower structure.
9) Describe the role of stomata and guard cells in helping plants obtain the gases needed for cellular respiration and photosynthesis.
10) Describe the role of transpiration in helping water move throughout a plant.
11) Explain how glucose is transported from the leaves to the roots.
12) Compare and contrast xylem and phloem in terms of structure and function.
13) Compare and contrast primary growth and secondary growth.
14) Describe the role of auxin in primary growth.
15) Compare and contrast phototropism and gravitropism and explain their role in plant growth.
