Biology, Eighth Edition (Raven)
Learning OutcomesChapter 42
- Describe how plants produce flowers in response to environmental cues.
- Explain meristems, competence, phase change, photoperiodism, the roles of different hormones, and how these different factors interact in the flowering process.
- Describe how flowers evolved. What are the parts of a complete flower?
- Discuss the three known genetically regulated pathways for flowering. What is the role of phytochrome in these pathways? List the evolutionary advantages provided by angiosperm flowers.
- Describe the two major evolutionary changes that led to the diversity of flower phenotypes.
- Differentiate between pollination and fertilization.
- Describe the processes of pollen formation and embryo sac formation.
- Explain fertilization in angiosperms.
- Understand the advantages of asexual reproduction in plants. What is apomixis?
- Name and describe the parts of a flower. Which part becomes the seed?
- Explain the life span of annual, biennial, and perennial plants.
- Differentiate between complete and incomplete flowers, and between monoecious and dioecious plants. Which arrangement promotes outcrossing?
- Understand the advantages of asexual reproduction in plants.
- Differentiate among annual, biennial, and perennial plants.
- Understand the process of abscission.
