Exam III Material/Chapter 12- Eukaryotes

The Eukaryotes are comprised of: Algae, Protozoa, Fungi, and Multicellular parasites.
I ALGAE
_a) are classified by their pigment
_b) Photosynthetic
__1)Dinoflagellates - (toxins) Red tide, Parasytic Shellfish poisons from shrimp, oysters and other "bottom-dwellers"
__2) Pfiesteria- sludge bug. When a gene is induced, they grow flagella, swim up to fish and secrete toxins, the scales are affected and fall off of the fish, the sludge bug devours the fish as a blood meal, then swims back down as flagella fall off in association with reproduction of other pfisteria.
II PROTOZOA
_a) are classified by their method of locomotion
Giardia, caused by deer and beaver urine infected stream water is an example of a protozoa.
III FUNGI
_a) are classified according to method of reproduction, it can be sexual or asexual
_b) they can be unicellular or multicellular- the multicellular can produce toxins (mushrooms)
_c) few are mobile, but some are airborne
IV MULTICELLULAR PARASITES
_a) have similar modes of transmission as bacterial helminths
_b) have parasitic behavior
_c) refer to Table 23:2 in the Bauman book.
