FUNGI CH 9 SEC 4
GOAL/PURPOSE AFTER COMPLETING THE LESSON, STUDENTS WILL BE ABLE TO NAME THE CHARACTERISTICS FUNGI SHARE EXPLAIN HOW FUNGI REPRODUCE DESCRIBE THE ROLES FUNGI PLAY IN NATURE
WHAT ARE FUNGI? • KEY- MOST FUNGI SHARE SEVERAL IMPORTANT CHARACTERISTICS • KEY- FUNGI ARE EUKARYOTES THAT HAVE CELL WALLS. • KEY- FUNGI ARE HETEROTROPHS THAT FEED BY ABSORBING THEIR FOOD • KEY- FUNGI USE SPORES TO REPRODUCE
Key- There are many different types of fungi. How many can you count?
List 3 types of beneficial fungi and 3 types of harmful fungi
CELL STRUCTURE • KEY – FUNGI RANGE IN SIZE FROM TINY UNICELLULAR YEAST TO LARGE MULTICELLULAR FUNGI. • HYPHAE- SINGULAR HYPHA- FUNGI ARE BRANCHING THREADLIKE TUBES THAT MAKE UP THE BODIES OF MULTICELLULAR FUNGI. • KEY- SOME FUNGI LIKE MOLDS GROW AND SPREAD THE HYPHAE OVER ITS FOOD SOURCE
CONT’D • KEY- OTHERS HYPHAE ARE MORE TIGHTLY PACKED AND APPEAR SOLID • EX- MUSHROOM • COPY AND LABEL FIGURE 25 FROM TEXT P. 345 • KEY- FUNGI ABSORBS FOOD THROUGH HYPHAE THAT GROW INTO A FOOD SOURCE
REPRODUCTION • KEY- FUNGI USUALLY REPRODUCE BY MAKING SPORES. • KEY- THE LIGHTWEIGHT SPORES ARE SURROUNDED BY A PROTECTIVE COVERING AND CAN BE CARRIED EASILY THROUGH THE AIR OR WATER TO NEW SITES
ROLE OF FUNGI IN NATURE • KEY- MANY FUNGI PROVIDE FOODS FOR PEOPLE. EX- MUSHROOM • KEY- FUNGI PLAY IMPORTANT ROLES AS DECOMPOSERS AND RECYCLERS ON EARTH. EX- BREAKDOWN PLANTS ON FOREST FLOOR • KEY- SOME FUNGI CAUSE DISEASE, WHILE OTHERS FIGHT DISEASE. EX- ANTIBIOTIC PENICILLIN AND PLANT DISEASE • KEY- SOME FUNGI LIVE IN SYMBIOSIS WITH OTHER ORGANISMS EX- ORCHID SEEDS NEED FUNGI TO DEVELOP.
COPY AND ANSWER THE FOLLOWING QUESTIONS • 1. HOW ARE THE CELLS OF A BREAD MOLD ARRANGED? HOW ARE THE CELLS OF MUSHROOM ARRANGED? • 2. HOW DOES A FUNGUS ABSORB FOOD? • 3. DESCRIBE SPORES AND THEIR ROLE IN REPRODUCTION OF FUNGI? • 4. NAME AND DESCRIBE SIX ROLES FUNGI PLAY IN NATURE. • 5. WHAT ARE LICHENS AND WHY DO SCIENTIST STUDY THEM?
