  1. Land plants ( kingdom          ) are a diverse group that evolved from        algae.

  2. Four innovations among the kingdom Plantae are:
    • Alternation of              , with multicellular, dependent          .

    • Multicellular            which produce spores.

    • Multicellular             which produce gametes.

    • Apical            in root and shoot systems.

  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.

    • Seedless vascular plants grew to great heights during the                period and may have led to global cooling.
