Cards

Term
Kingdom Fungi
Definition

-MONOphyletic Group

-Heterotrophic absorption

-Mycelium (veg state)

Chitin and Glycogen

ZYGOTIC MEIOSIS

Term

Phylum Zygomycota

 

Definition

Coenocytic Hyphae (no cross walls)

-Endomycorrhizae, decomposers, rots produce

SEXUAL OR ASEXUAL

Uses conjugation to create zgosporangium

Term
Phylum Ascomycota
Definition

-Septate Hyphae (simple cross walls)

-decomposers, plant pathogens, food, part of lichens.

-SEXUAL OR ASEXUAL W/ conidia

 

Term
Ascomycete Sexual Reproduction
Definition
Zygotic Meiosis with a SHORT delay between PLASMOGAMY & KARYOGAMY resulting in dikaryotic hyphae
Term
Ascocarp
Definition

Fruiting body of a mushroom.

Contains a mixture of haploid hyphae and dikaryotic hyphae 

Term
Hymenium
Definition

Makes up the hymenophore of mushroom

Fertile layer in an ascocarp that produces spores 

-dentate, smooth, poroid, lamellate

Term
Ascus
Definition

Sexual cells: site of Karyogamy, mitosis & meisos

 

Asci undergoes mitosis & meiosis to make 8 haploid spores

Term
Apothecium
Definition

Ascocarp with exposed hymenium.

Cup shaped

Term
Perithecium
Definition

Stroma: contains multiple ascocarps within one common structure.

Circular ascocarp with small opening. Many embedded in stroma

Term
Cleistothecium
Definition

Spherical ascocarp fruiting bodies 

Hymenium is completely enclosed

Term
Conidial Fungi Reproduction
Definition

Asexual with conidida 

(mitospores are produced externally)

Term
Conidial Fungi Importance
Definition
Medicine (penecillin), cheese, athletes foot, decomposers, miso and soy sauce.
Term
How are Conidial Fungi produced?
Definition
Mitosis
Term
What are examples of Conidial Fungi?
Definition
Aspergillus & Pennecillium
Term
What is the ploidy of Conidial Fungi?
Definition
Mostly Haploid
Term
Yeasts Reproduction
Definition
Asexual reproduction through budding
Term
Yeasts are....
Definition

Truly Unicellular

Produced by Mitosis

Term
Yeast Importance
Definition
Fermented beverages, baking, decomposers.
Term
Lichens
Definition
Stable mutualistic interaction between mycobiont and photobiont
Term
Mycobiont
Definition
Fungal component (usually an ascomycete)
Term
Photobiont
Definition
Photosynthesizer either composed of cyanobacteria or chlorophyta
Term
Cyanolichen
Definition
Mycobiont + Cyanobacteria
Term
Chlorolichen
Definition
Mycobiont + Cholophyta
Term
Crustose Lichen
Definition
Crust-like, scrape off, often on Alder trees.
Term
Foliose Lichen
Definition
Leaf life, 2 distinct sides.
Term
Fruticose Lichen
Definition
Shrubby, 3 Dimensional, all surfaces look alike.
Term
Tri-Partite Lichen
Definition
Mycobiont + Green Alga + Cyanobacterium
Term
Ecological Importance of Lichens
Definition
Rock Erosion, Soil development, Nitrogen fixation, Food (90% Caribou Diet), Nesting Material, Air quality indicators, Medicinal use, Dyes
Term
Phylum Basidiomycota Importance
Definition
Decomposers, plant symbiots (ECTOmycorrhizae), edible mushrooms, wood rot, poison
Term
Clamp Connections belong to which phyla? Purpose?
Definition
Clamp connections are present in basidiomycota and they hep maintain dikaryotic hyphae.
Term
What is the ploidy of basidiomycota feeding mycelium?
Definition
(n+n) Dikaryotic
Term
What is the name of a fruiting body of a basidiomycete?
Definition
Basidiocarp (entirely n+n)
Term
Hymenium
Definition
Spore producing layer of basidiomycetes containing basidia and cystidia
Term
Life cycle of Basidiomycota
Definition
ZYGOTIC meiosis through conjugation with a long delay between plasmogamy and karyogamy
Term
Hyphae of Basidiomycota
Definition
Septate Hyphae with dolipore septa and parenthesomes.
