Fungi

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 hyphae penetreate and anchor mycelium to bread Rhizoids also secrete enzymes that digest surrounding food then absorb digested nutrients

Bread Mould

Asexual Reproduction Develop 3 rd 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 (basidiomycotes)

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
