Nonvascular Plants and Seedless Vascular Plants Flashcards
Anatomical Adaptations for Living on Land
Vascular Tissue, Root system, Cuticle/cork, and Gas exchange
Vascular Tissue
Used to transport nutrients and water throughout a plant;
Xylem: water
Phloem: nutrients
Root System
Anchoring system, ability to absorb underground water and nutrients
Cuticle/cork
Protection; decrease water loss
Gas Exchange
pores that allow for gas exchange
Alternation of Generations
Diploid plant produces spores (Sporophyte) Haploid plant produces gametes (gametophyte)
Diploid
Sporophyte and Zygote
Haploid
Spores, Gametophyte, and Gametes
Generation or Phase
Sporophyte or Gametophyte
Bryophytes: Seedless Nonvascular Plants
Mosses, Liverworts, and Hornworts;
Water necessary for reproduction; Lack vascular tissue; No true roots, stems, or leaves; Can’t absorb water from the soil; Gametophyte Dominant
Seedless Vascular Plants
Ferns, Horsetails, and Lycophytes (club mosses); Have true stems, roots, and leaves; Sporophyte Dominant; Has Vascular Tissue
