Slime Molds Observe the plate of Physarum under the stereoscope and draw what you see. Describe any movement you see (this is a plasmodial slime mold).

LABORATORY REVIEW 15 1. What are two major differences between prokaryotic and eukaryotic cells? (2pts) 2. List the two major types of nutrition and give an example of a protist with this type of nutrition. (2pts) Nutrition Examples 3. List the three different structures for locomotion found among protozoans, and name an organism that utilizes each structure. (2pts) Structure Organism Name 4. Name two characteristics of slime molds by stating their mode of nutrition and how they survive conditions unfavorable for growth. (2pts) 5. Could an ecosystem that contains only protists remain in continued existence? Why or why not? Think specifically about how the organisms would consume their food i.e. obtain energy for living.
