Transcript

  • 1. Plant Phyla
  • 2. But before we get into phyla . . . To what domain do plants belong?  EUKARYA!! To what kingdom do plants belong?  Plants (Plantae) What are some characteristics that ALL plants share? – Cell nuclei (Eukarya) – Cell walls – Multicellular – Photosynthesis – Sexually Reproducing
  • 3. Introduction to Plants Plants are classified into four main group:1. Mosses and Liverwort (Bryophyta)2. Ferns (Pteridophyta)3. Conifers (Gymnosperms)4. Flowering Plants (Angiosperms) – All are different in appearance, structure and behaviour.
  • 4. Mosses - Bryophyta Mosses are non-vascular plants -- they cannot transport fluids through their bodies. Instead, they must rely on surrounding moisture to do this job for them. Though small in stature, mosses are very important members of our ecosystem. They lay the foundations for other plant growth, prevent erosion, and contribute to the lush green appearance of many forested areas.
  • 5. Mosses - 2 The 24,000 bryophyte species, sometimes grouped into a single phylum are now grouped in three phyla:1. Mosses (Bryophyta),2. Liverworts (Hepatophyta) and3. Hornworts (Anthoceraphyta). They reproduce by spores, never have flowers, and can be found growing on the ground, on rocks, and on other plants.
  • 6. Mosses
  • 7. Liverworts and Hornworts
  • 8. Life Cycle of the Moss
  • 9. The Fern - Pteridophyta Ferns have a vascular system to transport fluids through their bodies but like the mosses, they reproduce from spores rather than seeds. The main phylum, the Ferns (Pteridophyta) includes around 12,000 species. Three other phyla are included as fern allies: the Horsetails , Club Mosses and Whisk Ferns Ferns also have a gametophyte and sporophyte stage, but the gametophyte stage is very short.
  • 10. Conifers - Gymnosperms The gymnosperms reproduce from seeds instead of spores. The seeds, however, are "naked" (Greek: gummnos) -- not covered by an ovary. Usually, the seed is produced inside a cone-like structure such as a pine cone which is why they are called "conifer." Some conifers, such as the Yew and Ginko, produce their seeds inside a berry-like structure. Conifers are fairly easy to identify: In addition to cones, these trees and shrubs typically have needle-like, scale-like or awl-like leaves. And they NEVER have flowers.
  • 11. Conifers - 2 Approximately 600 species are counted as conifers including the pines, firs, spruces, cedars, junipers, and yew. Species within the conifer ranks give us pine nuts -- pestos magic ingredient -- as well as juniper berries for gin. Conifer allies include three small phyla containing fewer than 200 species all together: Gingko (Ginkophyta) Cycads (Cycadophyta) ; And herb-like cone-bearing plants (Gnetophyta) such as Ephedra.
  • 12. Angiosperms (Flowering Plants): Families Seed bearing plants of the Order Angiosperm are further classified into plant families. Plants belonging to the same family share a common trait, usually based on flower structure. The most important and common families are detailed next:
