Ascomycota TERM 2

Yeasts occur in what cellular

state?

DEFINITION 2 Unicellular TERM 3

Where do you find yeasts?

DEFINITION 3 Surface of plantssurface and guts of animalsPathogens of humans and other animals TERM 4

What type of spore does a yeast have?

DEFINITION 4 Ascospore TERM 5

How does the order Schizosaccharomycetales

reproduce?

DEFINITION 5 fission

Importance of yeasts

BrewingFood productionmodel systemsIndustrial applicationsAnimal pathogens TERM 7

Somatic Structure of Yeasts

DEFINITION 7 single celled fungus that reproduces by budding or fission TERM 8

Pseudomycelium

DEFINITION 8 Series of cells adhering together after budding TERM 9

True Mycelium

DEFINITION 9 produced through apical tip growth TERM 10

Asexual reproduction of yeasts

DEFINITION 10

  1. Budding Production of a small outgrowth from parent cell Multilateral- buds off of all sides in unorganized fashion Bipolar- buds only off of ends
  2. Conidia Asexual spore formed at the tip or side of sporogenous cell
  3. Arthrospores Asexual spore resulting from fragmentation

Mutual benefits of mychorrizae

Plant Effects increased water acquisition available phosphorus enhanced growth resistance to biotic stress Fungus Effects acquires carbon in the form of carbohydrates TERM 17

Arbuscular mychorrizae

DEFINITION 17 tree like formation in plant rootsHave large multinucleate sporesNon septate hyphaeSome form vesicles TERM 18

Intraradical hyphae

DEFINITION 18 grow within the root TERM 19

Extraradical hyphae

DEFINITION 19 grow outside the root TERM 20

Arbuscules

DEFINITION 20 highly branched, thin walled structures within host cell

colonization of mychorrizae TERM 22

periarbuscular membrane

DEFINITION 22 Where nutrient exchange happens, membrane surrounding arbuscular branches TERM 23

AM mychorrizae Spores

DEFINITION 23 can have 100's to 1000's of spores per nuclei per sporeExtra Large SporesNo evidence for sexual reproduction TERM 24 DEFINITION 24 Lichen cross sectionTop - CortexMiddle - Algal LayerBottom - Medulla TERM 25

How do algal and fungal cells reproduce

together?

DEFINITION 25 Soredia erupts from within the lichen, the fungal cells wrap around the algal cells

Isidia

photbiont containing projection from cortex TERM 32

Soredia

DEFINITION 32 noncortex combination of photobiont and mycobiont TERM 33

foliose licen

DEFINITION 33 leafy TERM 34

fruticose

DEFINITION 34 stalked, pendent or shrubbyhas a core TERM 35

Squamulose

DEFINITION 35 loosely attached lobes

Crustose

no lower cortex TERM 37

Gelatinous

DEFINITION 37 not stratified Cyanobacteria dispersed throughout the medulla TERM 38

Important uses for Lichens

DEFINITION 38 nesting and food sources for animals Dyes Essential oils and perfumes Medicines - antiviral and antibacterial TERM 39

Ectomycorrhizae

DEFINITION 39 has: Mantle, hartignet and Extraradical mycelium TERM 40

EcM Mantle

DEFINITION 40 Sheath of hyphae covering roots increases root surface area prevents water loss Do not produce vesicles

Hypogeous

having reproductive structures that remain underground TERM 47

Ericoid Mycorrhizae

DEFINITION 47 Unique to several families in the plant order Ericales Hyphal Coils in outer cells of hair roots No arbuscules, mantle or hartig net Only found in epidermal cells TERM 48

Mycohetertrophic

DEFINITION 48 Obtains nutrients from fungus only TERM 49

Monotropoid Mycorrihzae

DEFINITION 49 Occurs in achlorophyllous plants in momotropaceae form mantle and hartig net fungal pegs - hyphae that penetrate epidermal cells TERM 50

Orchid Mycorrhizae

DEFINITION 50 Only found in orchids Fungus essential for germination of seed (seed lacks endosperm) form coils called peletons within host ells potentially parasitic

What are the 4 fungal phyla involved in

mycorrhizae?

  1. Glomeromycota - AM only2. Basidiomycota - EcM, Monotropoid, Orchid3. Ascomycota - EcM, Ericoid4. Zygomycota - EcM TERM 52

Trichomycetes

DEFINITION 52 Obligate endosymbionts Mostly aquatic commensalism not an ecological group TERM 53

2 Fungal Orders

DEFINITION 53 HarpellalesAsellariales TERM 54

Hierarchical Classification

DEFINITION 54 Phylum -mycotaSubphlyum -mycotinaClass -mycetesOrder - alesFamily -aceae
