What did the broccoli say to the mushroom?????

You’re a … FUN-GUY... Or FUNGI … Or whatever … Ya, that was bad … Ok, let’s move on …

The Fungi

1. Characteristics Can’t move: sessile Multicellular (if singular called "yeast") Heterotrophic Don’t contain chlorophyll Eukaryotic Saprophytic: absorb their food from decaying matter (decomposers) External digestion (animals etc. have internal digestion) Have cell walls (made of chitin) Live in moist environments

2. Uses Keep the forest floor clear Make trees and plants grow faster (lichens) Food for humans (bread, cheese, wine, medicines)

3. Saprobes 1.Fungi can’t digest foods within their bodies. 2.Thus, fungi release digestive enzymes into the immediate environment 3.Enzymes break down dead organic matter. 4.Fungus then absorbs digested food through their cell walls.

4. Reproduction most reproduce asexually and sexually by spores spore: a cell that has a haploid number of chromosomes also reproduce sexually by the conjugation of hyphae to form a “zygospore”

Chytrids Most ancient of the fungi The only fungi with swimming spores Most are saprophytes (Rot growers) Obtain food from dead organic material Single Celled or Multicellular

Zygomycetes Include some familiar bread and fruit moulds Most are soil fungi Many used commercially Many are parasites of insectsinsects

Glomeromycetes All form symbiotic relationships with plant roots

Ascomycetes Many, such as yeast, are useful to humans Some cause serious plant diseases

Basidiomycetes Mushrooms, puffballs and bracket fungi Most are decomposers Some form symbiotic relationships with plants

Magic … Amanita Muscaria commonly known as the fly agaric or fly amanita a mushroom and psychoactive basidiomycete fungus
