Transcript of Fungi

What is Fungi?
A member of the large group of eukaryotic organisms that includes microorganisms such as yeast and molds, as well as the most familiar mushrooms.
Phylum A taxonomic rank below kingdom and above class.
Phylum has 3 kingdoms (Fungi, Plantae, Animalia. What is Plantae? Multicellular eukaryotes
cellwalls made of Cellulose
Auto-trophic
4 major groups(Mosses, Ferns, Cone-bearing plants and Flowering plants
First plants came from algae Characteristics Of Fungi Eukaryotic
Non-vascular organisms
Reproduce by means of spores, usually wind-disseminated.
Both sexual and asexual spores may be produced, depending on the species and conditions.
Alternation Of Generations. Cell wall
Cytoplasmic Ultras Three main typess Phylum Zygomycota
Common Molds Phylum Ascomycota
Sac Fungi Phylum Basidiomycota
Club Fungi Common Mold
Bread mold is one type
2 kinds of hyphae: the rhizoids & Stolons.
Looks "fuzzy"-small fruiting bodies.
Sexusl & asexual phases. Largest phylum
Yeast
Special structure called the ascus that forms inside the fruiting body-resembles cup
Yeast powder Specilized reproductive structure that resembles a club or umbrella; called basidium.
Fruiting bodies develop quickly.
Mushroom cap is lined with gills in the inside, lined with basidia which produce the spores.
Some are edible. some posionous. Four Major Groups:
Mosses
Bryophytes
No Vascular Seedless Life cycle depends on water for reproduction (sperm must swim to get to eggs)
Lack vascular tissue
Human Uses Ferns
Seedless Plants
Vascular Cone-bearing
Gymnosperms Flowering-plants
Angiosperms First plants to develop vascular tissue allowing water transport.
Use tracheids
Have true roots
Water to reproduce
Club mosses, Horsetails, and Ferns Means "Naked Seeds"
Leaves are needles that are adapted to dry conditions.
Most evergreen-don't shed leaves. All members of Phylum Anthophyta
Most recent of plant phyla.
Develop unique reproductive organs.
"Enclosed seed" What's Animalia? Multicellular, eukaryotic heterotrophs that lack a cell wall.
Most animal species are invertebrates(Lack back bone.)
Vertebrates(Have back bone).
Evolutionarily complex.
Radical symmetry or bilateral symmetry. What do animals do? Animals carry out certian life functions...

Feeding
respiration
Circulation
Excretion
REsponse
Movement
Reproduction THE DIFFERENT TYPES: PHYlum Cnidarian Jelly fish, sea anemones, corals.
Sofft-bodied, with stinging tentacles.
Live in water.
rely on hydrostaticskeleton.
radical symmetry.
Rerproduce sexually and Asexually.
Phylum Porifera Have holes.
Sponges: Most ancient animals, asymmetric.
Hollow. Dependent on the movement of water through the pores for feeding and respiration, circulation and excretion.
Filter feeders.
Sexual And asexual reproduction. Phylum Platyhelminthes Flatworms, Flukes, tapeworms.
Simplest animal with bilateral symmetry.
No more than a few mm thick.
Rely on diffusion for respiration.
Head has group of nerve cells that control.
Have eyespots.
hermaphrodites. Phylum nematoda Roundworms, hookworms, Trichinella, Filarial worms, heartworms, ascarid worms.
Free-living.
Pseudocoelom.
No internal transport system.
More senses organs that just light.
Reproduce sexually. phylum annelida Segmented worms( earthworms, leeches)
True coelom with a crop and gizzard.
Closed circulatory system
Breathe through skin
Reproduce sexually, some hermaphroditic

Phylum mollusca Snails, slugs, clams, squids, and octopi.
Soft-bodied(internal, external shell)
Have teeth
Nervous system varies greatly
Most reproduce sexually
