Sarcodina ENTAMOEBA HISTOLYTICA FOOD SOURCE IS HUMAN CELLS HALF OF WORLD INFECTED WITH AMOEBIC DYSENTERY THUS, CLEAN DRINKING WATER IS IMPORTANT, OR IT CAN BE TRANSMITTED LIVES IN 2 FORMS: TROPHOZOITE AND CYST ASSOCIATED WITH INTESTINE (TROPHO) FECAL-ORAL TRANSMISSION INFECTED INDIV WILL HAVE CYSTS IN FECAL MATTER; DEFECATE INTO WATER SOURCE, UNINFECTED INDIV WILL DRINK IT, THE CYST TRAVELS TO GUT AND BECOMES TROPHOZOITE; LIVE IN GUT LINING CAUSING INFLAMMATION SURVIVE IN PHAGOCYTOSIS LIKE MANNER, RESULTS IN AMOEBIC DYSENTERY. FECAL SAMPLE FROM AFFECT INDV WILL BE BLOODY AND MUCOUS FILLED. AMOEBA INVADES LINING OF GUT B/C IT WANTS RED BLOOD CELLS; BODY RESPONDS W/ INFLAMMATION =MUCOUS; GUT IS BLEEDING TO FEED TROPHO. Sarcodina Arcella sp HAS OUTER LAYER CALLED TEST AMDE OF CHITIN "MICROSCOPIC HERMIT CRAB) Difflugia sp ORIFICE AT TOP, PSEUDOPODIA AT BOTTOM FOOD IS DIGESTED INSIDE THE TEST IN PHAGOCYTIC FASHION USE FOR MOTILITY OF FOR NUTRITION Sarcodina have pseudopodia---reticulapodia, rhysopodia "root foot", used for attachment or food gathering=works like cytoplasmic streaming; not suitable for motility, Foraminifera "foram" have test, test is made of calcite mineral, different morphology, test is mutichambered test. Sarcodina test a Heliozoan with axopodia not for motility, more mechanism for food gathering and getting around envmt Radiolarians like forams, marine/aquatic. have a test, not made of calcium, it is made of silica. have single chamber test. have ability to predict where oil deposit are Sarcodina Axopodium like poles in organism, can fend off debris and settle, twirl then...
