Fungi
Classifying FungiOriginal ancestors unkniwn
Used to be included in plant kingdom
Grow in ground + have cell walls ( like plants)
Classified in 4
ZygomycotesIncludes: 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 MouldMade 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 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 (basidiomycotes)
Club FungiInlcude 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 Fungimushrooms 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
RepructionGills extend under the cap of the mushroom
