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
