Eukaryotic microbiology Flashcards
where do we think mitochondria came from
a endosymbiosis with the bacteria alphaproteobacteria
where do we think chloroplasts came from
an endosymbiosis event with cyanobacteria
what eukaryote keeps the primary producers regulated in an aquatic environment
dianoflagelates and ciliates consume 60% of microbes
how widespread are eukaryotes
found in every environment, but they are not as extreme as archea or bacteria.
what are sparotrophes
organisms that digest decayed material extracellularly. Fungi are saprotrohes
how do dinoflagellates consume bacteria
carbon is fixed into a mucousphere which attracts bacteria. the bacteria then get trapped in the mucousphere and are digested by phagocytosis
what is myzocytosis
when a cell sucks the cytoplasm out of another cell to digest its nutrients. The switch from phagocytosis to myzocytosis was caused by multicellular structures growing too big to engulf.
