Briefly describe the essential elements of the scientific method. - Observable facts, testable hypothesis, controlled and replicated experiment, interpretation of the results, others repeat that work. 2. Describe one characteristic that fungi have in common with animals and one characteristic they have in common with plants. Also indicate to which of the two groups (plants or animals) fungi are most closely related. - Fungi are more closely related to animals. - They share immobility with plants. - Like animals they can’t create their own food. - Fungi have cell walls like plants. 3. What are the principal functions of fungal hyphae? - Nutrient acquisition: they secret enzymes that digest food and then absorb the products of digestion. 4. What is meant by the term trophic growth? - Nutrient acquisition and growth are tightly linked. 5. In what ways can spores function in the life-cycle of a fungus? - Reproduction - Dispersal - Survival 6. Describe two different means by which fungal spores can be dispersed. - Passive (i.e. dispersed by wind, stuck to an animal or insect) - Active (i.e. forcible ejection) 7. Would you expect fungi relying on wind dispersal to produce larger or smaller quantities of spores than fungi that are dispersed by attachment to insects and why? - Wind dispersal has greater risk & greater opportunity.
