Plants Flashcards
What are the two types of land plants?
Bryophytes and tracheophytes
Non-vascular land plants
Bryophytes
Vascular land plants
Tracheophytes
Include mosses, liverworts; non-vascular; low to ground, form “mats”; photosynthetic phase is the haploid (gametophyte) phase
Bryophytes
Reproduce with spores; have roots, stems, leaves; include ferns, horsetails, clubmosses
Seedless tracheophytes (spores)
Divided into two groups: gymnosperms and angiosperms
Seed tracheophytes
What two groups are seed tracheophytes divided into?
Gymnosperms and angiosperms
Non-flower producing
Gymnosperms
Flower producing
Angiosperms
Reproduces via exposed seed (ovule); seed is exposed on a reproductive structure, usually a cone (pine cone); approx 1000 species, conifers, ginkgo, cycad, mormon tea, etc…
Gymnosperm
Largest and most diverse group of plants (approx. 80% of all land plants); flowering plants; the ovule is fertilized and develops into a seed inside a protected ovary (ovary usually inside flower)
Angiosperm
All plants are …?
Eukaryotic, multicellular, have chloroplasts, use photosynthesis
