| Question | Answer |
|---|---|
| Most fungi are... | Mulitcellular |
| Cells are... | Eukaryotic |
| Cell walls are made up of.... | Chitin |
| Organisms are anchored to a... | Substrate |
| There are no true | Tissues |
| Spores are produced in the | Sporangia |
| These spores will eventually | Germinate |
| Each haploid spore generates a | hypha |
| if two hyphae run into each other it creates a | Mushroom |
| Heterotrophic or Autotrophic | Heterotrophic |
| Do they photosynthesize | no |
| Most are saprophytes. Explain | They obtain food from decomposing dead organic matter. |
| They use extracellular digestion. Explain. | The hypae break down dead organic matter around them and then absorb the nutrients through diffusion. |
| Are spored haploid or diploid? | Haploid |
| What type of sexual reproduction do yeast perform and why. | since yeast is unicellular they reproduce by budding. |
| What are the 6 classifications of fungi? | Threadlike, Sac fungi, Club fungi, Imperfect fungi, Glomeromycetes, and chytrids. |
| Describe Threadlike fungi. | They produce spores in their hypae. |
| Describe Sac fungi. | Produce spores in structures that look like sacs. |
| Describe Club fungi. | Produce spores in structures that look like clubs. |
| Describe Imperfect fungi. | They cannot reproduce sexually. |
| Describe Glomeromycetes. | Fungi that always form symbiotic relationships with plants. |
| Describe Chytrids. | The only fungi with free swimming spores. |
| Give an example of threadlike fungi. | Bread and Fruit molds. |
| Give an example of Sac Fungi. | Yeast |
| Give an example of Club fungi. | Mushrooms |
| Give an example of Imperfect Fungi. | Penicillin |
| The role of fungi in ecosystems is as a... | Decomposer |
| State 4 uses of fungi. | Food, fermentation, medicine, and as symbioants |
| State 3 diseases caused by fungus. | Athlete's foot, peanut fungus and dutch elm disease. |
