Cards

Term
Fungi- Reproduction
Definition
Reproduce sexually and asexually (facultative lifecycle); Stages are morphologically distinct; no predetermined size or age; Fungi live inside their food; pleomorphic; only 1 sexual stage morphology but 1-many asexual stage morphologies
Term
Fungi- Kingdom
Definition
Eukaryotic, achlorophyllous, NEVER phagotrophic, osmotrophic/absorptive; Mitochondria have flattened cristae; lask ameboid pseudopodial stage; cells walls contain chitin and beta-glucas; Flagella have no retronemes;
Term
Fungi-Production of a Chitinous Cell Wall
Definition
"Radical invention"; forced shift from phagotrophy to osmotrophy which enabled translocation and chemotrophism;
Term
Fungi- Four Major Phyla
Definition
***Classified by sexual state;
1. Ascomycota 2. Basidomycota 3. Zygomycota 4. Chytridiomycota
Term
Oomycetes
Definition
Pseudofungi/lower fungi; Heterotrophic stamenopiles
Term
Mycetozoans
Definition
Slime molds; Acellular slime molds, cellular slime molds and protozoa
Term
Thallophyte
Definition
Plants that have no stem, roots, or leaves; Thallic somatic organization
Term
Thallus
Definition
The vegetative body of a thallphyte; used to designate somatic organization of a fungus
Term
Hypha
Definition
Term
Mycelium
Definition
Term
Rhizomorph
Definition
Term
Stroma and Sclerotia
Definition
Term
Microfungi
Definition
Molds and yeasts
Term
Macrofungi
Definition
Mushrooms, toadstools; Basidiomycetes, ascomycetes
Term
Teleomorph
Definition
Sexual stage;"Perfect state"
Term
Anamorph
Definition
Asexual state; "Imperfect state"; "Mitosporic state"
Term
Plasmogamy
Definition
Union of two protoplasts
Term
Karyogamy
Definition
Fusion of two nuclei together; forms diploid stage; Meiosis restores haploid stage;
Term
Nuclear Cycle
Definition
Haploid or Diploid
Term
Parasexuality
Definition
Heterokaryosis; Expression of multiple phenotypes
Term
Ascus; Asci
Definition
Asomycota;
Term
Basidium; Basidiospores
Definition
Basidiomycota
Term
Zygosporangium; Zygospore
Definition
Zygomycota
Term
Mitosporic fungi
Definition
Anamorphic fungi; deuteromycetes; No sexual stage known; parasexual; some of the most frequently encountered fungi; ascomycetes, basdiomycetes; produce asexual spores (conidia); identified by development, morphology of conidiogenous cell and conidia.
Term
Ascocarps; Cleistothecia, Perithecia, Apothecia
Definition
Naked asci; Cleistothecia (closed hollow spheres); Perithecia (flask-like); Apothecia (cup or disk-like)
Term
Basidiocarps
Definition
Term
Conidia
Definition
Asexual spores produced by mitosporic fungi
Term
Hyphomycetes
Definition
Mitosporic fungi; conidia produced on exposed conidiophores
Term
Agonomycetes
Definition
Mycelial forms which are sterile but produce differentiated vegetative structures;
Term
Coelomycetes
Definition
Produce conidia in conidiomata
Term
Chytridiomycotina
Definition
Produce motile cells (zoospores); Flagella: single, posterior, whiplash-type; coenocytic thallus; conversion of zygote to resting spore or sporangium; most are aquatic; saprotrophs or parasites
Term
Saprotrophs
Definition
Term
Fungal Physiology
Definition
Chemoorganoheterotrophs; Osmotrophic nutrition; Exoenzymes; Absorb nutrients broken down by exoenzymes
Term
Exoenzymes
Definition
Nutritional functions; attack mechanism for parasites; morphogenic function in cell wall metabolism
