-
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
-
-
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
