Plants evolved from freshwater green algae.
The green algae split into two major - the chlorophytes (which never made it to land)
groups: - the charophytes (sister to all land plants)
Streptophytes charophytes and land plants
Cuticle a waxy or fatty, noncellular layer (formed of a
substance called cutin) on the outer wall of
epidermal cells.
Stomata In plants, a minute opening bordered by guard
cells in the epidermis of leaves and stems; water
passes out of a plant mainly through the stomata.
Sporophyte The spore-producing, diploid (2n) phase in the life
cycle of a plant having alternation of generations.
Gametophyte in plants, the haploid (n), gamete-producing
generation, which alternates with the diploid (2n)
sporophyte.
, What distinguishes gamete formation Gametes in plants are produced by mitosis. Human
in plants from gamete formation in gametes are produced directly by meiosis.
humans?
Bryophytes A moss, liverwort, or hornwort; a nonvascular plant
that inhabits the land but lacks many of the
terrestrial adaptations of vascular plants.
Liverworts a nonvascular plant that's shaped like a human liver.
found growing as a thick crust on moist rocks or
soil along the sides of a stream.
archegonium the multicellular egg-producing organ in
bryophytes and some vascular plants.
antheridium a sperm-producing organ.
hornwort a member of the phylum Anthocerophyta, a unique
group of bryophytes that grow close to the ground
in moist, shady areas and that are characterized by
long, thin, photosynthetic sporophytes
What might account for the Mosses are extremely desiccation tolerant and can
abundance of mosses in the Arctic withstand a lack of water. Also, freezing
and Antarctic? temperatures at the poles are less damaging when
mosses have a low water content.
phloem vascular tissue that conducts sucrose and
hormones throughout the plant.
xylem vascular tissue that carries water and dissolved
minerals upward from the roots to every part of a
plant
