I. Objectives At the end of the period, the students should be able to: A. identify the defining characteristics of fungi; B. describe the main structures of a fungus; C. distinguish fungi according to the kind of fruiting structures they form; D. explain briefly how fungi reproduce; and E. give the benefits and demerits of fungi. II. Subject Matter Topic: Kingdom Fungi References: Biology Teacher’s Edition by Miller et al, pg. 527 Materials: illustration, printed materials, thread ball ( a representation) III. Procedure Teacher’s Activity A. Motivation Have you eaten a pizza with mushrooms?
Students’ Activity Yes/No.
Have you seen the gray to black or white spots on a three-day old bread left in a warm place? Which kingdom of organisms do these mushroom and molds belong? B. Presentation When you first saw a mushroom, have you thought of it as a fungus right away? If not, then where did you classify it? C. Lesson Proper In your lower years, fungi were already introduced to you. What type of organisms are they? What are the evidences that fungi are not plants?
Yes/No. Kingdom Fungi.
Yes/No. Plants.
They are Eukaryotes. They do not have chlorophyll thus, cannot produce their own food.
What else?
Some are parasites.
How do you say so?
Because they survive by living on a host organism.
How else do they obtain energy?
Other fungi feed on dead and decaying organic matter.
What do you call these types of fungi in this mode of nutrition? 1. Pre-activity Let’s have an educational guessing game. I have here an illustration of a mushroom. Different parts will be
Saprotrophs/Saprophytes.
provided to you that will serve as choices to what will be defined later on. You may read your references or biology books while I prepare the materials. 2. Activity proper 3. Post-activity This is a vegetative portion of a fungus with long slender filaments that resembles threads.
(Read their references and biology books.)
(Each may be called to post their answers on the board.) Hypha/Hyphae.
This is a net-like mass of connected hyphae.
Mycelium/Mycelia.
This is a dome-shaped upper part of some fungi.
Cap.
This is a thin radiating plate on the underside of the cap of a mushroom that produces microscopic spores. This is the stem-like feature supporting the cap of a mushroom. This is the poisonous part found on the stalk. This is the visible fungus that is usually the reproductive structure. How do fungi reproduce? What aid these spores to be carried in the environment? Sexually, how do these fungi reproduce? In bread mold Rhizopus, where are spores produced?
Gills. Stalk. Ring. Fruiting body. They undergo asexual reproduction by forming buds and many spores. Wind, water, animals, or humans. They reproduce sexually when male and female hyphae join together. Sporangium. Ascus.
How about yeasts, where are their spores produced?
Ascopore.
How are yeast’s spores called?
Basidium.
Where are mushroom spores produced?
Basidiospore.
What do you call their spores?
D. Generalization Identify and define the different parts of a mushroom.
E. Application Give examples of fungi and its uses.
Saccharomyces rouxii and Aspergillus oryzae are utilized in soy-sauce making. Trichoderma harzanium used to speed up the decomposition or organic materials. Penicillum notatum is used in making penicillin, a drug that kills disease-causing bacteria.
Give examples of harmful fungal species and its effect.
Aspergillus flavus which produces the aflatoxin, a poisonous substance, if foods like moldy corn or peanuts are ingested, poultry and humans can be poisoned and may also cause liver cancer. Trichophyton mentagrophytes and T. rubrum cause athlete’s foot. Trichophyton rubrum can also cause ringworm.
Ringworm can be acquired in a moist public places where people go barefoot. Give an example of this place.
Swimming pool.
IV. Evaluation [Understanding] 1. Justify why fungi is not a plant. 2. What is the advantage of the large numbers of spores produced by fungi? V. Assignment Answer the following questions: 1. Do plants have chloroplasts? 2. What are plants’ cell walls made of?
