Diversity of Life II

Chlorophytes

Green Algae: Embryos are unicellular

Tracheophyte

Trees, Ferns, Flowering Plants: plants with water transport and vascular system

Lychophytes

Ex: Selaginella, Tracheophyte with Roots, stems, leaves, unbranched vein, no fern or seeds

Gymnosperms

Seed plants but no flowers and no fruit, Ex: Norfolk Pine

Angiosperms

flowering plants and fruits

Nontracheophyte

Moss: No tissue for water transport

Porifians/Parazoa

No Tissues

Eumatazoean

Tissues

Cnidarians

Two Tissue/Radial Symmetry, Ex: Hydras, jellyfish and corals

Protosomes

Developed mouths first

Deutrostomes

Developed mouths after anus

Coeloms

Organisms with mesoderms cells lining the inner tubes of digestive tract and body wall

Acoelomates

Organisms with filled space between tubes of digestive tract and body wall

Pseudocoelomates

Organisms with empty space between tubes of digestive tract and body wall

Chordates

Organisms with a supportive rod that develops for back like snake, birds, humans

Echinoderms

Deutrostomes with water-vascular system like sea stars, sea urchins, sand dollars

Nonmolting Coelemates

Earthworms, mollusks

Nonmolting pseudocoelomates

Rotifers/philodina

Nonmolting Acoelomates

Flatworms

Molting Pseudocoelomates

Roundworms/Ascaris

Molting Coelomates

Arthopods/Crustaceans, Crabs, Insects, Spiders

Mitosis

Process that creates diploid plants

Meiosis

Process that creates haploid plants

Gameophyte

Haploid plant that produces gametes, larger than sporophyte

Sporophyte

Diploid plant that grows from zygote
