Plant Life Cycle
Two-staged: Sporophyte & Gametophyte
Plant Classification
Vascular
non-Vascular
Non-Vascular Plants
Grow low
Require moisture & shade
No vascular tissue; xylem/phloem
Examples of Non-vasculars
The Three Groups of Non-
         vascular Plants...
Mosses
Liverworts
Hornworts
Vascular Plants
Can grow tall
Water, nutrients, minerals, sugars move in
vascular tubes.
3 Types...
1. Seedless Vascular Plants
 Reproduce with spores
Seedless Vascular
 Ferns
 Horsetails
Seed Plants:
Characteristics...
         Have vascular tissue
         Reproduce with seeds and pollen
Two types...
      Gymnosperms
      Angiosperms
2. Gymnosperm Vascular Plants
Reproduce with seeds stored in a cone
Means “naked seed”
Seeds function in
plant survival of harsh
conditions
Gymnosperm types...

 Conifers
 Cycads
 Ginkoes
 Gnetophytes
Seed Structure
Embryo = fertilized egg

Cotyledon = becomes leaf, may store food for growing embryo.
Gymnosperm life cycle...
3. Angiosperm Vascular Plants
Reproduce with seeds stored in a fruit
Angiosperm fruit types..
More fruits with seeds...
Angiosperm flower structure
Know all these words by heart-quiz
Angiosperm life cycle...
The two types of angiosperms
Roots...
Stems...
Woody stem...
Leaf structure...
Controlling water loss...
Stomata are pores on the underside of leaves.
Transpiration is water loss from a plant.
Stomata control gasses going in and water leaving a plant.
Photosynthesis involves gasses, glucose, and water...
Stomata under a leaf...
