FUNGI READING NOTES – CHAPTER 11.2 Directions: Read pages 255-261 and complete the following reading notes. Draw pictures to help you remember each vocabulary word. (YOU WILL LOSE POINTS IF YOU DO NOT DRAW PICTURES!) General Characteristics: Way of getting food: eukaryotic consumers; come in a variety of shapes, sizes and colors; all have similar ways of reproducing & getting food, some decomposers but others are parasites live on or near food supply. Most secrete digestive juices (enzymes) onto food source & then absorb dissolved substances (nutrients) An example of symbiosis is fungi that grow on the roots of plants; release acid that changes Mineral in soil into forms the plant can use & protect plant from disease causing organisms Hyphae is: (define & draw) Mycelium is: (define & draw) chains of cells that make up multicellular fungi (similar to plant roots); have holes in cell walls that allow cytoplasm to move freely between cells twisted mass of fungal hyphae that that have grown together; often underground REPRODUCTION Asexual Two types: (describe) 1.) The hyphae break apart & each new piece becomes a new individual. 2.) Spores (small reproductive cells coated by a thick protective membrane) are released - carried wind; forms new fungus where spore lands. Sexual: (describe) Special structures form to make sex cells; sex cells join to produce sexual spores that grow into new fungus KINDS OF FUNGI: Classified by: shape & way it reproduces Four main groups: (describe & give examples) 1.) Thread-like shapeless, fuzzy fungi, most live in soil & usually decomposers – some parasites (ex. molds) Reproduction: asexual or sexual Spores help: the organisms reproduce (Sporangia protect spores in unfavorable conditions) 2.) Sac Fungi largest group, most multi-cellular but some singlecelled (ex. yeast); Ex: yeasts, powdery mildew, truffles & morels Reproduction: asexually or sexually (form a sac called an ascus that contains spores) ;most use both during the lifetime Budding: is asexual reproduction in which a new cell pinches off of an existing cell (Ex. Yeast) Uses to humans: Yeast in bread, sources of antiobiotics, vitamins, edible (truffles & morels) Can cause parasitic diseases in plants (chestnut blight & Dutch elm disease) 3.) Club Fungi Umbrella shaped, commonly known Reproduction: asexual (rare) and sexually basidia are: special hyphae where reproductive spores form during sexual reproduction Examples: mushrooms, bracket fungi, puffballs, smuts & rusts 4.) Imperfect Fungi Fungi not found in other groups, Reproduction: asexually, most are parasites (can cause disease) Examples: athletes foot, penicillum (antibiotics), and aflotoxin (causes some cancers) Uses: medicine, cheese, soy sauce & citric acid LICHENS Description: combination of fungus and algae that grow intertwined. Has a symbiotic relationship. Produce food through: photosynthesis Where they live/needs: almost everywhere, only need air, light, and minerals They indicate air quality easily affected by air pollution – die in poor conditions because:
