Classifying Fungi • Original ancestors unkniwn • Used to be included in plant kingdom • Grow in ground + have cell walls ( like plants) • Classified in 4
Zygomycotes • Includes: saprotrophs: absorbs nutrients from inanimate sources • Also: moulds, parasites of protists and small invertebrate animals • Small black dots • Reproduce both asexually and sexually • Keep sexual reproduction in reserve
Sexual Reproduction • Produce zygospores • Thick wall develops around the nuclei fuse to protect contents from dying • Zygospore is dormant until exposed to adequate growing conditions • Absorbs water and nuclei undergo meiosos
Bread Mould • Made up of two forms of hyphae • Stolons are horizontal hyphae. They spread over the bread surface • Rhizoids are downward growing hyphaepenetreate and anchor mycelium to bread • Rhizoids also secrete enzymes that digest surrounding food then absorb digested nutrients
Asexual Reproduction • Develop 3rd form of hyphae called sporangiophores that extend above the myclium • They carry sporangia ( sprore bearing capsulees) • Asexual Spores develop inside the sporangia • Then it is released when capsules split open
Club Fungi • Inlcude mushrooms that grow on lawns, bracket fungi on dead trees, puffballs and stinkhorns on woodland floors • Short lived reproductive structures called fruiting bodies or basidiocarps • Bear spores called basidospores located on club shaped hyphae called basidia • Some club fungi are parasites to plants and do not form basidiocarps
Club Fungi • mushrooms seen growing on ground not the whole thing vast network of hyphae spread underground • Basidiospores are releas and when they land on a suitab;e environment begins to grow and produce hyphae • 2 different types of hyphae
Repruction • Gills extend under the cap of the mushroom
