Unit 5: The Evolutionary History of Diversity Plant Diversity I: How Plants Colonized Land Review
  1. Land plants (kingdom ) evolved from algae, and are most closely related to the . Five innovations among the Plantae are:
  2. Bryophytes lack tissue with three phyla of small herbaceous plants: (Hepatophyta), (Anthocerophyta), and (Bryophyta ).
    • The large produce gametes which fuse to yield small .
    • Sporophytes produce haploid which grow to become the .
    • Male gametes are flagellated that short distances to fertilize the egg.
  3. Vascular plants evolved in the period, and have life cycles with dominant ; their spores develop into bisexual .
  4. Vascular plants possess specialized vascular tissues called and .
    • Xylem contains dead cells called and elements which carry water and minerals up from the system through the system.
    • Phloem includes living cells arranged into tubes that distribute and other organic products from the .
  5. Seedless vascular plants 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.

Unit 5: The Evolutionary History of Diversity Plant Diversity II: The Evolution of Seed Plants Review
  1. Seed plants are : different kinds of spores produce reduced male and female , which in turn produce .
    • Megaspores develop into which contain female gametophytes, microspores develop into grains which contain male gametophytes.
    • When a pollen grain is transferred to the part of a plant containing the , it can germinate and discharge two 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 or animal .
  2. Gymnosperms (conifers) bear “naked” , typically on , and include four phyla: Cycadophyta, Gingkophyta, Gnetophyta, and Coniferophyta.
  3. The gymnosperm life cycle shows a dominant generation, grains transferring to ovules, and the development of from fertilized .
  4. Angiosperms are seed plants that possess reproductive structures called and .
    • A flower is a specialized with modified leaves.
    • A Fruit typically consists of a mature with seeds. 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.
