20.1: Fungi What is a fungus? The Characteristics of Fungi Fungi are eukaryotes, use spores to reproduce and are heterotrophs. Fungi need moist, warm places to grow Most are multicellular, yeasts are unicellular Hyphae: branching threadlike tubes that make up the bodies of multicellular fungi Fuzzy looking molds have loosely tangled hyphae. The stalk and cap of mushrooms are closely packed hyphae. Mycelium: a complex network of branching hyphae may serve to anchor the fungus, invade food sources, form reproductive structures Cell walls of must fungi contain a complex carbohydrate called chitin Cross walls called septa divide hyphae into individual cells that contain one or more nuclei Pores in the septa let cytoplasm, organelles and nutrients flow throughout the fungus

Lecture 5 ? Kingdom of Fungi HW 1. Explain what a pseudohypha is. -A chain of yeast formed when buds remain attached in a row. 2. Explain what a ?dimorphic fungus? is. -It can take either form (yeast or hyphae), depending upon growth conditions, such as changing temperature. 3. What are mycoses? Fungal infections in the way the agent enters the body and the degree of tissue involvement. 4. What are the three most common sexual spores? -Zygospores, ascospores, and basidiospores 5. Give six types of asexual mold spores. -Arthrospore; Chlamydospore, Blastospore, phialospore, micro/macroconidium; porospores 6. What are zygospores?

Christina Krucylak Fungi Problem Set AP Biology April 2, 2013 Fungi are heterotrophs and therefore cannot make their own food, like plants can. They absorb nutrients from the outside environment. They use enzymes to either breakdown complex molecules into simpler ones for easier absorption or to break down cell walls or membranes to absorb nutrients from a host. Fungi have a wide range of ?hosts? and they can range from parasitic relationships to mutualistic ones. Hyphae are a network of tubular membranes surrounding the plasma membrane and cytoplasm of cells. This network is both above and below ground. A mycelium is more or less the subterranean part of a hyphae tube network. A mycelium infiltrates the material on which the fungus feeds off of.
