Objective: Kingdom Fungi. Fig Fungi Characteristics The most common body structures are multicellular filaments and single cells (yeasts) Eukaryotes.
Fungi Chapter 31. Fungi More closely related to animals than plants Unicellular Most are multi-cellular Tropics to tundra Aquatics to terrestrial.

Kingdom Fungi Eukaryotic, cell walls made of chitin, saprophytic or parasitic and essential as decomposers.
“The Mighty Mushroom” take a walk through a forest mushrooms are truly are the largest organisms in the forest Kingdom Fungi: – not just mushrooms! – approximately.
Fungi. Fungal Characteristics: Eukaryotic Multicellular Kingdom Feed by Absorptive Nutrition Tubular cell shape, called Hyphae –Septate or aseptate hyphae.
Fungi. Fleshy fungi Yeasts Molds –Hyphae (long filaments of joined cells) –Mycelium (intertwined mass of hyphae)
True Fungi break down dead organic material provide numerous drugs foods like mushrooms Plant and animal diseases.
Overview: Mighty Mushrooms Fungi are diverse and widespread They are essential for the well-being of most terrestrial ecosystems because they break down.
Fungi Lab. Tentative Phylogeny Fig 28.8 Generalized fungal lifecycle Spore-producing structures Spores ASEXUAL REPRODUCTION GERMINATION Zygote Mycelium.
Classification of Fungi. Fungi are more closely related to animals than plants: Animals and fungi have flagellate cells Animals and fungi have flagellate.
Diversity of Fungi More than 100,000 species of fungi are known and mycologists estimate that there are actually about 1.5 million species worldwide. Molecular.
Fungi. General Characteristics Primarily terrestrial Filamentous –__________ Coenocytic (aseptate) septate –mycelium –Haustoria – specialized parasitic.
Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings Body Structure The morphology of multicellular fungi – Enhances ability to absorb.
Fungi Decomposers, Mutualists, and Killers. Fungi –(most) degrade dead organic matter –form nutritional partnerships with most vascular plants & some.
