The challenges to live on land and the will to survive The sun can be brutal!
I can: compare and contrast the moss and fern life cycle Do Now: classify the following as vascular or nonvascular: ABE CD.
22.1 Plant Life Cycles KEY CONCEPT All plants alternate between two phases in their life cycles.
The World of Plant Classification An Unusual Angiosperm.
Origin of the Land Plants. Alternation of Generations.
Ferns Alternation of generations Zygote created from egg & sperm.
First land plants Bryophytes: mosses & liverworts –non-vascular no water transport system no true roots –swimming sperm flagellated sperm –lifecycle dominated.

The Early Tracheophytes: Ferns and Relatives. Tracheophytes (Early and Late) - Tracheophytes are vascular plants that posses, lignified water conducting.

Early vascular plants (fossil record) branched sporophytes –dichotomous branching –terminal sporangia rhizome = horizontal stem still attached via rhizoids.
ALTERNATION OF GENERATIONS. 1.Alternation of generations: haploid (n) stage that produces gametes followed by diploid (2n) stage producing spores. 2.Haploid:
