what are the differences and similarities of Archaea and Eukaryotes nuclear envelope- E multiple linear chromsomes- E membrane enclosed organelle- E branches membrane lipids-a peptidoglycan- / Eukaroytic RNA polymerase- E, A core histones- A, E where did protists diversity come from Endosymbiosis Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:15 Full screen Endosymbiosis certain unicelluar organisms engulf other cells and build a relationship up until the point where they become organelles within the host cell what does endosymbiosis indicate after the original engulfment there was another in which eukaryotes acquired a photosynthetic cyanobacterium which evolved eventually into plastids what two lines of photosynthetic protists does endosymbiosis give rise to red algae and green algae what fact is this supported by the DNA of plastids found in the two types of algae above resemble that in cyanobacterium what did the red and green algae undergo during evolution secondary endosymbiosis secondary endosymbiosis were ingested in the food vacuoles of heterotopic eukaryotes and became endosymbionts (reliant on each other) as well. what do Eukaryotic cells have nucleus and other membrane bound organelles what dot he organelles provide in eukaryotic cells specific locations in which particular cellular functions are performed eukaroytic cells lead to more... complex and organized structure than prokaryotes The organisms in most eukaryotic lineages are protist most protists are what unicellular what are protists unique eukaryotes protists are large or small eukaroytes small are protists motile yes protists are not polyphonic. true or false False what are protists related to plants, fungi, and animals are protists diverse and numerous yes the first eukaryotic was a single cell protists are abundant, small, or few in ecosystems abundant what are protists good important/good for important for photosynthesisers major predators of prokaryotes parasitic protists cause some major disease what is the internal organization and DNA in prokaryotes simple in both internal structures and the physical arrangement of their dan what do prokaryotes not have compartmentalization membrane bound nucleus what do the specialized membranes perform in prokaryotes metabolic functions who has more dna prokaryotes or eukaryotes eukaryotes what does the genome consist of in prokaryotes circular chromsomes with a few proteins where is chromosome locate in prokaryotes nucleiod plasmids smaller rings of replicating DNA the DNA replication, transcription and translation is close to what eukaryotes when do prokaryotes reproduce quickly in favourable environments what do prokaryotes reproduce through binary fission binary fission single cell divides into two cells, which then continue to divide what type of generation time do prokaryotes have short what does short generation times allow for lots of evolution in small periods of time what do their chemical and biological adaptations allow them to do live in environments with little competition what do certain bacteria develop resistant cells called endospores when do bacteria develop these cells when lacking essential nutrient what do endospores help bacteria survive in tough environments initially prokaryotes have many ways of gaining energy from extreme environments what are they autotrophs, photoautotrophs, chemoautotrophs,hydrothermal vent ecosystems autotroph means what self feed autotrophs -need only CO2 in some form as a carbon source
