Contd
  • Plants also grouped according to how they obtain
    water.
  • Vascular plants have tube-like structures that
    transport water from the roots to the leaves.
  • Nonvascular plants can only absorb water through
    their roots.

21
Nonvascular plants
  • Nonvascular plants or bryophytes are found in
    moist areas because they do not have long roots
    to absorb water.
  • They are usually less than 20 cm tall.
  • Three classes
  • Mosses
  • Liverworts
  • Hornworts

Vascular Plants
  • Two categories
  • Gymnosperms bear seeds in cones pine trees
  • Angiosperms (Flowering) largest category- bear
    seeds in flower

Angiosperms
Commonly called flowering plants Two
types monocots one seed leaf dicots two
seed leaves Fruit ripened ovary of a
flower Includes trees, grasses, and shrubs
31
First Plants
  • Oldest fossils (450 million years) show that
    earliest plants were similar to todays mosses
  • Early plants depended on water for reproduction
  • Over time plants evolved adaptations that allowed
    them to reproduce without water and also to
    exist in a wide range of terrestrial environments.

32
Origins in water
  • First plants evolved from multicellular green
    algae.
  • These algae have the size, color, appearance of
    plants
  • Reproductive cycles of algae like plants
  • Cell wall and pigments of algae identical to
    plants
