Exam 2 Ch 29 Plant Diversity I: How Plants colonized land
1. Know Basic characterisitcs
Domain Eukarya
Kingdom Plantae
Bryophytes (nonvascular plants) Phylum
Hepatophyta (liverworts) Phylum
Anthocerophyta (hornworts) Phylum
Bryophyta (mosses) Seedless vascular
plants
Phylum Lycophyta (club mosses, spike mosses, and quillworts) Phylum
Pterophytes (ferns, horsetails, and whisk ferns): ...
2. 29.1
• Describe four shared derived homologies that link charophyceans and land plants
<answer> Rosette-shaped cellulose-synthesized complexes.
Peroxisome enzymes. Structure
of flagellated sperm. Formation
of a phragmoplast.
1/6
, 3. • Describe four characteristics that distinguish land plants from charo- phycean
algae <answer> Alternation of generations and multicellular, dependent embryos.
Walled spores produced in sporangia.
Multicellular gametangia. Apical
Meristems.
4. • Define and distinguish among the stages of the alternation of generations life
cycle <answer> Gametophyte produces haploid gametes by mitosis.
2 gametes unite and form a diploid zygote.
The zygote develops into a multicellular diploid sporophyte. The
sporophyte produces haploid spores by meiosis.
The spores develop into multicellular haploid gametophytes.
5. 29.2
• List and distinguish among the three phyla of bryophytes <answer> • Bryophytes
are represented today by three phyla of small herbaceous (nonwoody) plants
o Liverworts, Phylum Hepatophyta
o Hornworts, Phylum Anthocerophyta
o Mosses, Phylum Bryophyta
6. Liverworts (Phylum Heptophyta): Liver-shaped gametophytes. Some
