    (nonvascular)

  • Phylum Anthocerophyta

    Hornworts

    (nonvascular)

  • Phylum Bryophyta

    Mosses

    (non vascular)

  • Seedless vascular plants

    Leaves, roots, and stems

    Have spores

  • Bryophytes

    First nonvascular land plants

  • Gymnosperms

    vascular plants with naked seeds

  • Dioecious

    Male plant and female plant

  • Monoecious

    Male and female parts on one plant

    1. Vascular

    2. Ground

    3. Pith

    4. Epidermus

    1. Transport

    2. Storage of water and nutrients

    3. Center of the stem directing water and nutrients

    4. Protection

  • Cuticle

    waxy covering that prevents evaporation

  • Tracheids

    transport water and dissolved minerals from the roots to the rest of the plant

  • Xylem

    transports water and dissolved minerals upward from the roots

  • Phloem

    distributes sugars and amino acids produced by photosynthesis throughout the entire plant

  • Parenchyma

    living, thin-walled cells responsible for metabolism, photosynthesis, and food storage

  • Sclerenchyma

    dead, thick, lignified cells that provide rigid structural support and protection to the plant

  • Collenchyma

    provides flexible, plastic structural support without restricting growth, allowing plant organs to bend in the wind.

  • Sieve tubes

    transport sugars and organic nutrients from leaves to the rest of the plant

  • Cotyledon

    embryonic leaf within the seed

  • Hypocotyl

    embryonic stem of a germinating stem
