Plant Growth and Reproduction

Framing Question

How do plants grow and develop?

Learning Objectives

  • Explain when and where in the plant meiosis occurs.
  • Categorize examples of asexual reproduction based on the plant structures involved.
  • Select a plant and diagram the contributions of the gametophyte(s) to sexual reproduction.
  • Support the claim that plants continue to develop and differentiate new structures after formation of a multicellular structure by drawing and identifying regions of a plant with persistent meristem activity.
  • Using examples, explain how shoots and roots are repeatedly added to a plant through meristem activity.
  • Categorize internal and external cues based on their effects on plant form.
  • Draw a diagram that represents the effect of a specific wavelength of light on plant form; include photoreceptors, signal transduction, gene expression, and morphological change in the diagram.
  • Draw a diagram that illustrates the effect of gravity on plant form; include receptors, signal transduction, gene expression, and morphological change in the diagram.
  • Identify the categories of plant hormones and provide examples of their effects on growth and development.
  • Compare and contrast the production of and response to a steroid hormone in a plant and an animal.
  • Diagram how internal and external cues integrate to contribute to mechanisms of cell expansion.
