Name_____________________________ Per____ Chapter 22 – Fungi – Study Guide Review from Ch. 19 Due: ____________ Kingdom Fungi multicellular except for unicellular yeast cell walls of chitin (found also in exoskeleton of arthropods) composed of long slender strands of cells that share cytoplasm called hyphae (form “body” of fungus) reproduce asexually and sexually, means of reproduction is how fungi are classified remember myco = fungi; mycete also = fungi heterotrophs –secrete digestive enzymes on a substrate and absorb the nutrients; many are saprophytes (live on dead or decaying organisms) or parasites (live on living organisms) - no chlorophyll (not green) Complete the chart below using p. 421 Kinds of Fungi Phylum Reproductive Characteristics Examples & Diagrams Zygomycetes - Basidiomycetes Ascomycetes Answer the following questions using chapter 22, beginning with p. 482. 1. Fungi are heterotrophic. Evidence of this involves what fungi do NOT have as well as what processes are evident in their metabolism. What do fungi NOT have? 2. Describe the body of a fungus and the relationship between hyphae and mycelium. P. 483 . 3. What polysaccharide found elsewhere only in the arthropods is also found in the cell walls of fungi? ___________________ How is this different from plant cell walls? _______________ 4. Fungi can be ________________, living on dead and decaying organisms, or they can be ____________________, living on or in another organism, possibly causing disease. 5. Fungi can cause disease and destroy food. What can fungi do that is valuable? 6. What are spores? ___________________________ What natural resource do fungi depend on to spread their spores? ___________ p. 484 7. How do yeast reproduce (p. 487)? ____________ Is this asexual or sexual? _____________ Fungal Partnerships What is a symbiotic relationship? What is mutualism? Briefly explain two examples of mutualism involving fungi. Section: Fungal Partnerships Fungi Assessment Quiz Holt Biology © Holt, Rinehart and Winston In the space provided, write the letter of the description that best matches the term or phrase. Some choices may be used more than once. _____ 1. include a photosynthetic partner _____ 2. a symbiotic relationship between two living things _____ 3. found underground _____ 4. one partner is a fungus _____ 5. one partner is a plant (often a tree) _____ 6. neither partner benefits _____ 7. includes an alga A. B. C. D. mycorrhizae lichens both mycorrhizae and lichens neither mycorrhizae and lichens In the space provided, write the letter of the term or phrase that best completes each statement or best answers each question. _____ 8. Plants can grow successfully in infertile soils if the plants have which of the following? A. truffles B. mushrooms C. lichens D. mycorrhizae _____ 9. In mycorrhizae, the hyphae penetrate the outer cells of a plant’s A. leaves B. roots C. stems D. fruits _____ 10. The algae in lichens provide the ability to use which of the following to make carbohydrates? A. water B. air C. chitin D. sunlight Analyzing the Effect of Mycorrhizae Background Two groups of plants were planted in similar soils under similar conditions, but group A was grown in sterilized soil and group B was grown in nonsterilized soil. After 18 weeks of growth, a photograph was taken of the plants. Examine the drawing and answer the following questions. Group A Group B Analysis 1. Compare the growth of the two groups. Which grew larger & faster? 2. Explain why one group grew better than the other group? 3. Critical Thinking – Inferring Relationships – Suggest a possible cause of slower growth in the small plants. 4. Recommend a course of action to restore growth in the stunted plants.
