Bryophytes

• Mosses

2

• Mosses are Bryophytes, nonvascular plants that
  grow only in moist environments.

3

• A moss attaches to the ground by small rhizoids
  (RY zoydz). These are rootlike structures found
  in bryophytes.

4

• Rhizoids are not true roots because they do not
  have vascular tissue to carry water.

5
These processes are slow and support only a small
plant.

• glucose travels between cells by diffusion.

• Water travels through a moss by osmosis,

Moss Life Cycle
7
In the first stage, spores develop into separate
male and female gametophytes.
8
The male gametophyte grows spermproducing sex
organs, and the female gametophyte grows
egg-producing sex organs.
9
The sperm cells use water from rain or dew to
swim to the egg cell and fertilize it. The
fertilized egg remains in the female sex organ
and develops into a sporophyte.
10
The sporophyte, still attached to the female
gametophyte, grows a stalk with a capsule on the
end.
11
In the capsule, cell divisions produce spores
that will be released to continue the cycle.
