1 Kingdom Fungi
2 Fungi come in many shapes and sizes and can grow almost anywhere!! Mycology
Characteristics 3 eukaryotic Singled celled heterotrophic multicellular absorption Most reproduce Sexually Asexually Cell wall …chitin Spores Spores
5 Made of Chitin (a carbohydrate)
6 Modes of Nutrition Heterotrophic Absorption Saprotrophs Parasitic
Three fungal lifestyles: 7 • A fungus that feeds ondeadorganic matter is asaprotroph. • Fungi that get their nutrients from living organisms do so in avarietyof ways but can be put into two broad categories. • If there is some benefit toboththe fungus and the other organism, the fungi aremutualistic. • Where there is no benefit to the other organism, the fungus is aparasite.
8 • Cattle, like other some other animals such as goats, deer, and giraffes, have billions of microbes inside their guts which help them digest their food • The large microbe is a type of protist. • The creature that looks like a tadpole attached to the side of the protist is a fungal spore. • The smaller, rod-shaped beasts lining the underside of the protist are bacteria.
Associations between fungi and plants 9 • Mycorrhizaeare symbiotic relationships between fungi and plant roots (the term means literally 'fungus root'). • Perhaps more than 80% of the species of higher plants have these relationships
Lichens • Mutualistic relationship between a fungus and an algae (or a photosynthetic bacteria).
10 • Parasitic fungi • Some species are predatoryfungi that live in the soil and ensnare animals such as nematodes (roundworms) in a loop of hyphae. • Human-Athletes foot, ringworm
11 Fungi are important decomposers in the environment Nutrient RECYCLERS
12 Reproductive structures • Spores • Sexual & asexual Each spore has the potential to generate another individual of the species.
Spores can be spread out (dispersed) by wind, water, & animals.

14 “True Fungi”
16 “Molds and Mildews”
Usefulness of Fungi • Fungi are valuable economically as a • Antibiotics, vitamins • various industrially important chemicals, such as • Acetone, Enzymes • fermentation processes, as in the production of • alcoholic beverages, vinegar, cheese, bread dough • Extremely important in soil renewal, through • the decompositionof organic matter 17
Yeasts • single cells, produce daughter cells either by buddingorbybinary fission • the common baker's yeast- Saccharomyces cerevisiae 18
20 The antibacterial effect of penicillinwas discovered by Alexander Fleming in 1929. He noted that a fungal colony had grown on an agar plate streaked with the bacterium and had killed the bacterium
21 Fairy Rings The mycelium grows in a circle and mushrooms grow on the edges of the mycelium, so the mushrooms grow in a circle! Something COOL.
