1. Protists

2. Alteration of generations-requires two structures Conjugation- direct exchange of DNA Differentiate two ways Protists reproduce sexually Sexual- alteration of generations Asexual-Mitosis Distinguish a sexual and sexual reproduction in Protists Appear similar to PA&F, but lack complex organization Identify unifying features of Protists fresh water, salt water (marine), damp soil List three environments where Protists are found Eukaryotic, some autotrophic, some heterotrophic. Live in water List characteristics of Protists

3. Dino- marine, plankton, two flagella Zoo- one flagellum at least, parasitic species, Euglenoids- some auto some hetero, light sensitive, flexible pelicle Differentiate three types of Flagellates Classified according to their pigments: Green, Red and Brown Contrast thee kinds of algae Silicon shelled photoautotrophs, divide in half until too small, sharp shells Describe the structure of diatoms Using pseudopodia, and cytoplasm streaming Identify how amoebas and forams move

4. Medicines works some, but developing resistance Control mosquito population, works but can cause other problems if too widespread Evaluate methods of controlling malaria Infected mosquito bites, sporozites got to liver, make merozoites these enter RBC’s and burst them in 24-48 hr cycles Summarize how malaria is transmitted Giradasis, Malaria, Toxoplasmosis, African sleeping sickness Name three diseases caused by Protists Human disease, livestock disease Identify two ways that Protists affect human health
