Framing Question

How does variation among plants affect survival and reproduction?

Learning Objectives

  • Compare the relative contributions of recombination, mutation, hybridization, and polyploidy to plant diversity.
  • Explain the biological constraints for hybridization and polyploidy to successfully increase plant diversity.
  • Explain how epigenetic phenomena such as DNA methylation and histone modification lead to phenotypic variation among plants that are otherwise genetically identical.
  • For various species that exhibit a range of diversity, predict some possible outcomes of expansion of their distribution due to climate change.
  • If a new pathogen or herbivore is introduced, predict possible outcomes for a plant species, relative to its diversity.
  • Categorize symbiotic relationships that have adapted plants to life in a terrestrial environment.
  • Compare strategies that have evolved for population migration and dispersal in mosses, ferns, gymnosperms, and angiosperms.
  • Select and evaluate an adaptation in plants for retaining water while facilitating gas exchange.
  • For an aquatic plant, select, and evaluate an adaptation for retaining gases needed for photosynthesis.
  • Compare structures and their modifications in desert plants from the southwestern U.S. and South Africa.
