D1. Engineer a fungus that would make it a killer parasite of plants. Describe the morphological, biochemical, reproductive, and life history features of your fungus and how they effect plants. You may include illustrations to support your ideas.

D2. We have encountered many organisms in this course that utilize “hygroscopic” structures to aid spore dispersal. Use examples and diagrams to describe as many of these organisms and their hygroscopic mechanisms as you can.

D3. Describe the transformations in the earth’s atmosphere that have facilitated the colonization of land by plants. Use dates from geologic history of the earth to present your answer chronologically. Give specific examples of organisms that have been critical in these transformations.

D4. Describe and give examples of biological interactions between algae, fungi, or mosses that have been instrumental in the evolution of new species.
