1. Non Vascular Plants

2. What are Nonvascular Plants Traits of Nonvascular plants: 1)No vascular tissue 2)May have leaf like structures but without vascular tissue they have... -

3. What are Nonvascular Plants Traits of Nonvascular plants: 1)No vascular tissue 2)May have leaf like structures but without vascular tissue they have... -no true leaves (leaflike) -no true roots (rootlike) -no true stems (stemlike) 3) Gametophyte is dominant

4. Limits of Non Vascular Plants Height Limits: No “pipe work” to bring water to higher parts of plants so plants stay short. Habitat restrictions

5. Limits of Non Vascular Plants Height Limits: No “pipe work” to bring water to higher parts of plants so plants stay short. Habitat restrictions: Lack waxy cuticle layer. Need moist places so leaflike parts do not dry up. Some have a dormant period that allows them to survive dry weather.

6. Two main groups of non vascular plants 1) Liverworts Two types: Leafy and Thallus

19. Adaptation and Importance 1)Able to thrive mircohabitats. -eg. Small cracks in a concrete wall or a small pit in tar roof Importance:

20. Adaptation and Importance 1)Able to thrive mircohabitats. -eg. Small cracks in a concrete wall or a small pit in tar roof Importance: - Create areas for other organisms to live -Pioneer species in primary succession.

21. Adaptation and Importance 1)Able to thrive mircohabitats. -eg. Small cracks in a concrete wall or a small pit in tar roof Importance: - Create areas for other organisms to live -Pioneer species in primary succession.  Moss moves in  Over time moss starts to die  Dead moss creates topsoil which allows other plants to move in

22. Adaptations and Importance 2) Holds water -Dead mosses contain empty spaces. These empty spaces fill with water. Importance -Increases the amount of water available for plants -Used by humans to increase moisture content in garden soil

23. Adaptations and Importance 3) Grows in shaded forests Importance -Retains moisture by blocking evaporation  Forests don’t dry up as fast
