Member of the Bryophyta, a division of the
plant kingdom containing three classes, the
Hepaticae (liverwort), Musci (moss), and
Anthocerotae (hornwort). Bryophytes are
generally small, low-growing, terrestrial
plants with no vascular (water-conducting)
system as in higher plants. Their lifecycle
shows a marked alternation of generations.
Bryophytes chiefly occur in damp habitats and
require water for the dispersal of the male
gametes (antherozoids). The sporophyte,
consisting only of a spore-bearing capsule on
a slender stalk, is wholly or partially
dependent on the gametophyte (the familiar
moss or liverwort `plant') for water and
nutrients. In some liverworts the plant body
is a simple thallus, but in the majority of
bryophytes it is differentiated into stem,
leaves, and rhizoids.
