Fungi
Eukartoytic multicellular
Lack photosynthesis
Get nutrients and water from absorption
Classified based on differences in reproductive structure
Saprobes
Absorbs nutrients from non living
Parasitic
Absorbs nutrients from living host
Hyphae
long strand of cells that are attached end to end
May make large networks
Mycelium
Fungal mat
Zygoycetes
Reproduction occurs with male and female structure both on separate hyphae
Plasmagamy
Cytoplasm of male and female fuse
Gametangia
Reproductive parts hyphae contain several haploid nuclei
Cytoplasm of male ad female fuse, followed by fusion of haploid nuclei
Ex
: mycorrhizae
Karyogamy
Fusion of haploid nuclei
Only happens when conditions are favorable
Ascomycetes
Also known as sac fungi
Female gametangia receive haploid nuclei from male, female start to grown rapidly into hyphea adn make asci
Asci
closed compartments where karyogamy takes place
Ascosphores
Asci that divide by mitosis
Basidiomycetes
Mushrooms
Basiocarps- Large umbrella shape reproductive bodies
Asexual spores under basicocarps
Hypae stretched undergrond
Haploid hyphae meet spores released from mushroom
Dikaryotic Hyphae
Having nuclei from two parents, grow into new hyphea
Molds
Are rapid growing fungi that reproduce only asexually
Yeasts
Are unicellular fungi that inhibit moist environments
Reproduce vis budding
Lichens
Combination of fungus and algae living together in one organism
Algal cells make sugar and nutrients for themselves while the fungus absorbs water and house algae
First colonizers of landscapes after fire and extremely hardy but sensitive to man made pollution
Reproductive sexually and asexually using spires and alternation of generations
