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

Adaptation and Importance

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

Importance:

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
