Transcript of Kingoms

Kingdom Fungi Phylum Zygomycota Phylum Ascomycota Phylum Basidiomycota bread mold sexual and asexual phases in life cycle two kinds of hyphae (rhizoids & stolons largest phylum nail fungus special structure called ascus specialized reproductive structure that resembles a club or umbrella some poisonous some edible mushrooms Kingdom Plantae 1. Bryophytes (Mosses) 2. Seedless Vascular Plants (Ferns) 3. Gymnosperms 4. Angiosperms depends on water; sperm
has to swim to eggs Phylums: Bryophyta, Hepitcophyta,
Anthocerophyta 1st plants to develop vascular tissue
allowing for water transport Phylums: Lycophyta, Arthrophyta, Pterophyta "naked seed"; evergreens Phylums:Coniferophyta, Gnetophytes, Cycads, Ginkgoes flowers Phylums: Anthophyta Kingdom Animalia multicellular, eukaryotic heterotrophs that lack a cell wall 95% invertebrates (lack a back bone
(insects, jellyfish, worms, etc.) Vertebrates
(fish, birds, mammals, reptiles) Phylum Cnidarian
live in water
soft bodies
stinging tentacles around their mouths
reproduce sexually and asexually
(ex: jellyfish) Phylum Porifera
no cell wall
filter feeders
reproduce sexually or asexually (budding)
(ex: sponges) Phylum Platyhelminthes
most no more than a few mm thick
flat and thin
rely on diffusion for respiration, excretion, and circulation
head has a group of nerve cells that control, but not complex enough to be called a brain
have eyespots (group of cells that can tell light or dark)
hermaphrodites (female and male organs) Phylum Nematoda
free-living in land and water
(ex: hookworms) Phylum Arthopoda
breathe through spiracles- opening along the body that connect yo tracheal tubes that branch inside (Spiders have book lungs, aquatic arthopods have gills)
Have developed heart and open circulatory systems
Have well developed nervous system and brain that controls groups of muscles
Sexual reproduction done in- or externally
Classified based on number and kind of body segments and appendages
Insects undergo metamorphosis during life cycle- transform from egg to nyph or larva/pupa; then to adult
Segmented body, exoskeleton, jointed appendages
Exoskeleton made of chitin and can be leathery (caterpillar) or very hard (crab, beetle, etc./ Organism molts when it gets too large; sheds exoskeleton andn grows a new, larger one.)
Evolved to have less segments, less legs and more specialized legs (Legs specialized into atntennae, claws, wings, mouthparts, stinger tails, spinnerets, etc.)
Wide arry of adaptations let arthopods eat a variety of foods
Ex: butterfly) Phylum Chordata
Must have four key characteristics
Dorsal, hollow nerve cord
runs along back, branches to connect internal organs, muscles, brain, etc.
long supporting rod below nerve cord (usually found only in embryos)
replaced by backbone in vertebrates
Pharyngeal pouches
paired stuctures in the throat
Tail that extends beyond the anus
at some stage in life, all have a tail
(ex: human beings)

Phylum Echinodermata
skin stretched over bony endoskeleton
five-part radial symmetry
water vascular system carries out respiration, circulation and movement
no cephalization- simple nervous system
separate sexes, external fertilization
(ex:sea urchins, sand dollars, sea stars, and sea cucumbers
