Fungi - Answer-Kingdom composed of heterotrophs -Eukaryotic - devoid of chlorophyll - obtains nutrition through absorption -typically reproduces through spores Number of fungal species estimation - Answer-approx 1.5 million Septum - Answer-cross wall cytoplasm organelles cross through Hyphae - Answer-The branching, threadlike tubes that make up the bodies of multicellular fungi - Blastocladiomycota -zygomycota -zoopagomycota -ascomycota -basidiomycota Mycellium - Answer-ma...

What is the primary ecological function of fungi? - Answer-degradation The characteristic cell of fungi that grows via polarized growth is the - Answer-hypha You encounter a species of fungi you do not immediately recognize. If you were to attempt to sexually cross this fungus with another known fungus to determine its species, you would be using this concept to identify it: - Answer-biological species concept Within its cell wall a true fungus has this characteristic molecule: - Answer...

Explain the primary ecological role of fungi - Answer-recyclers/degraders, break down complex organic compounds into simple molecules, minerals, and energy, elements are then reused by other organisms List the structural components of plants that fungi can degrade - Answer-Cellulose Lignin Pectin Cutin Nutritional succession - Answer-zygomycetes > simple sugars ascomycetes > cellulose basidiomycetes > cellulose and lignin R-selected - Answer-Species that reproduce early in...

Cellulose - Answer-complex carbohydrate which is the major constituent of plant cell walls (produced by the enzyme cellulase) Lignin - Answer-the binding agent which holds plant cell walls together, primarily in wood (produced by the enzyme ligninase) Pectin - Answer-binding agent between plant cell walls, primarily in fruit (produced by pectinase) Cutin - Answer-the waxy material which covers the epidermal cells of plants (produced by cutinase) White Rot - Answer-a type of wood rot ...

oomycota - Answer-not "true fungi", characterized by production of thick-walled oospores and the production of mobile flagellate asexual spores (zoospores), more closely related to algae, cell walls contain cellulose, nuclei are diploid, no septa oospore - Answer-sexual spore of oomycete zoospore - Answer-mobile, flagellate asexual spore of oomycete, have 2 flagella oogonium - Answer-"female" part of oomycete sexual reproduction; contains oospores antheridium - Answer-"male" pa...

Mycology - Answer-the study of fungi Fungus - Answer-a eukaryotic, heterotrophic organism, devoid of chlorophyll, with chitin in cell walls, that obtains its nutrients by absorption, usually reproduces by spores and usually exhibits a pronounced polarization of growing cells Eukaryotic - Answer-cell with a distinct nucleus Prokaryotic - Answer-cell with no nucleus, genetic material is free-floating Mycelium - Answer-collection of hyphae Hyphae - Answer-collectively comprise myceli...
