Diversity, Change and Continuity Flashcards
What four major groups can plants be classified into
Bryophytes, pterophytes, gymnosperms, angiosperms
What features would determine what groups plants are put into
Vascular tissue True leaves and roots Dependence on water for reproduction Seeds or spores Cones or flowers Fruit
What plant group is a moss
Bryophyte
Characteristics of bryophytes
No vascular tissue No true roots,stems or leaves No strengthening tissues Homosporous Depends on water for fertilization Alternations of generations
Which generation is dominant of Bryophytes
Gametophyte which is photosynthetic therefore produces gametes
What adaptions are needed for terrestrial plant life
Cuticle prevents water loss
Roots adsorb water and nutrients
Vascular tissue conduct and distribute these nutrients and water
Supporting tissues help hold up the plant for maximum sunlight
What are the main differences between non vascular and vascular plants
Possess vascular tissue which would form a central column in the plant
The sporophyte phase is larger and more conspicuous generation of the life cycle
How are vascular plants classified
Seedless plants (pterophytes) Seed bearing plants ( cone-bearing, gymnosperm or flowering plants, angiosperm)
