Document Summary
Abstract: eukaryotic include all organisms that have membrane bound organelles. Especially a nucleus with chromosomes made of dna in complex histones. The engulfed cell survives within the host and becomes an organelle with the organism: there are five subgroups within the domain eukaryotes: excavata, rhizaria, unikonta, Generally by absorption: algae autotrophs, use photosynthesis as their primary source of nutrition, supergroup excavata, have a reduced mitochondrian, include parasite, predatory and photosynethic forms. Giardia lamblia : parasite diplomonad, have 8 flagella, 2 separate nuclei, mitoses and no plastids, lifestyle includes an active feeding stage trophozoite, transmitted through water, in humans causes beaver fever. 1. 2 euglenozoans: main distinguishing factor is a spiral inside their flagella. 1. 2a kinetoplastids: whiplike flagella, have single centrally located nucleus, contain and kinetoplast, which contains extranuclear dna within a large single mitochondrian, symbiotic and heterotrophs. Trypanosoma : parasite, found in circulatory systems of animals, ribbon like organisms, undulating membrane the nucleus and the kinetoplast.
