Classifying Plants:
-Aquatic or Terrestrial-Prevention of Water Loss-Spores or Seeds-Vascular or Nonvascular
![Page 4: Plants…an Overview!](https://reader036.vdocuments.site/reader036/viewer/2022062501/56816666550346895dd9f9eb/html5/thumbnails/4.jpg)
Nonvascular Plants:-mostly terrestrial-produce spores-need water to reproduce-very small plants
Phyla:Bryophyta…mossesHepatophyta…liverwortsAnthocerophyta…hornworts

Vascular Seedless Plants:-have xylem and phloem-spores-can grow largerthan nonvascular plants
Phyla:Psilophyta…whisk fernsLycophyta…club mossesSphenophyta…horsetailsPteridophyta…ferns

Vascular Seed Plants:-Gymnosperm Angiosperm-have xylem and phloem-seeds (unprotected vs. protected)-nonflowering & flowering-can grow largerthan nonvascular plants
Phyla:Cycadophyta…Cycads (gymnosperm)Ginkgophyta…Gingkoes (gymnosperm)Coniferophyta…Conifers (gymnosperm)Gnetophyta…Cone-bearing, odd (gymnosperm)Anthophyta…Flowering (angiosperm)
