What are Nonvascular Plants
Traits of Nonvascular plants: 1) No vascular tissue2) 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
Limits of Non Vascular Plants
Height Limits: No “pipe work” to bring water to higher parts of plants so plants stay short.
Habitat restrictions
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.
Two main groups of non vascular plants
1) LiverwortsTwo types: Leafy and Thallus

Gemma cups Hold gemma (cells capable of forming new plants)
Gametophyte Hold egg and sperm
Two main groups of non vascular plants 2) Mosses

Asexual Reproduction: Reproduce by fragmentation.

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

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