Document Summary
Euglenoids - 1 of earliest organisms w/ mitochondria. 1/3 have chloroplasts, are autotrophic; rest are heterotrophic. Can become heterotrophic when left in the dark. Pellicle - flexible structure made up protein strips that change the organism"s shape. Reproduction through mitotic cell division (nuclear envelop stays intact) Stigma - light-sensitive organ that helps euglenoids move. Kinetoplastids - has single mitochondrion in each cell. Mini/maxi circles of dna in each mitochondrion trypanosomes - causes african sleeping sickness, east coast fever, Able to change antigens on glycoprotein coat to fool antibodies. Don"t infect the flies that carry them. Cellulose-like material forms plates that surround the cell. Apicomplexes - spore-forming parasites on animals inread invented by teads. Microaerophils - cells that grow best in low-oxygen, high-carbon dioxide areas. Plasmodium - responsible for malaria, best-known apicomplex. Gregarines - attaches to intestines of arthropods, annelids, mollusks. Ciliates - has large number of cilia. Heterotrophic, w/ cilia in rows or spirals around the cell.
