Kingdom: Fungi

Domain Eukarya

General characteristics

* Classification criteria

* eukaryotes 

* heterotrophs

* feed by absorption

* mostly multicellular

* except unicellular yeasts

* cell wall

* chitin

* rigid polysaccharide

* sexual & asexual reproduction

Fungal Structure 

* Fungal body 

* mycelium 

* thread-like cells

* hyphae

* Cells

* multiple nuclei

* Cell wall 

* chitin

* just like crab shells

Internal structure

* Eukaryotic cells

* long, thread-like cells

* filamentous

* incomplete divisions between cells

* septum

* multiple nuclei

Modes of Nutrition

* Heterotrophic

* secrete digestive enzymes 

* feed by absorption

* parasites 

* feeding on living creatures

* predators

* paralyzing prey

* decomposer

* breakdown dead remains

Fungal Diversity

Ecological Roles

* Decomposers

* recycle nutrients

* Symbiotic Relationships

* lichen

* fungi + algae

* cyanobacteria or green algae

* pioneer species in 

ecosystems

* makes soil from bare rock

* mycorrhizae

* fungi + plants

* enables plants to absorb more water

Mycorrhizae

* Critical role in plant growth

* extends water absorption of roots

Reproduction

* Asexual 

* budding in yeast

* Sexual

* spores

* spread by wind

* joining of + & – haploid spores
