How do mosses get water?



Mosses and Liverworts are
nonvascular
cling to damp soil, sheltered rocks, and
shady sides of trees
No roots but they are anchored in one
place by the rhizoids hair like fibers
that are like roots, they take in water
from their surroundings


Water travels directly from one cell to the
next
Mosses and Liverworts are seedless plants


spores cells that can develop new organisms
Seedless vascular plants have long tube like
cells that let water and food move easily
What are ferns?



leaves called fronds they grow above
the ground from and from and
underground stem called a rhizome.
roots grow out of the rhizome.
bottom sides of the fronds are covered
with spores.
How do the life cycles of
mosses and ferns differ?


Reproduce means to make new
There are 2 separate stages of
reproduction in the life of a moss and
liverwort

Spore production: this is called asexual
reproduction because it only needs one
type of cell to reproduce (A52)



Fertilization: this is when a male sex cell joins a
female sex cell
The stage that requires fertilization is called
sexual reproduction. This is when the plant
needs both the male sex cell and the female sex
cell to reproduce. (A53)
The process of going from sexual to asexual
reproduction is called alternation of
generations.
