Chapter 29 Plant Diversity I: How Plants Colonized Land Review
  1. Land plants ( kingdom ) are a diverse group that evolved from algae, and are most closely related to the .
     
     
     
     
  2. Four innovations among the kingdom Plantae are:
     
     
     
     
     
     
     
     
  3. Bryophytes lack tissue with three phyla of small herbaceous plants.
     
     
     
     
    • The large gametophytes produce which fuse to yield small .
       
       
       
       
    • Sporophytes produce haploid which grow to become the .
     
     
     
     
  4. Vascular plants possess specialized vascular tissues called and .
     
     
     
     
  5. Seedless vascular plants have life cycles with dominant and form two phyla.
     
     
     
     
    • Lycophyta includes mosses, mosses, and .
       
       
       
       
    • Pterophyta includes , , and ferns and their relatives.
     
     
     
     
  6. Seedless vascular plants grew to great heights during the period and may have led to global cooling.

Chapter 30 Plant Diversity II: The Evolution of Seed Plants Review
  1. Seed plants continued the evolution of smaller in the of generations.
     
     
     
     
  2. Gymnosperms bear "naked" , typically on .
     
     
     
     
  3. The gymnosperm life cycle shows a dominant generation, grains transferring to ovules, and the development of from fertilized .
     
     
     
     
    • Microspores develop into gametophytes.
       
       
       
       
    • Megaspores develop into gametophytes.
       
       
       
       
    • When a pollen grain is transferred to the part of a plant containing the , it can germinate and discharge into the female gametophyte within the ovule.
       
       
       
       
    • This process of is called and results in a containing a sporophyte .
       
       
       
       
    • The pollen eliminates the need to swim through water and allows for wide by .
       
       
       
       
      Review and exercise:
     
     
     
     
  4. Angiosperms are seed plants that possess reproductive structures called and .
     
     
     
     
    • A flower is a specialized with modified leaves and may produce fruits.
       
       
       
       
    • Fruits are adapted for seed by , , or animals to new locations.
     
     
     
     
  5. The angiosperm life cycle includes a fertilization which produces a food-storing in addition to the .
     
     
     
     
  6. Most angiosperms are and , classified by the number of (seed leaves).
