Endosymbiosis Study guides, Class notes & Summaries

Week 2: Prokaryotic and Eukaryotic Endosymbiosis Animal cell mitochondria • If you chose animal cells, how are mitochondria replicated within eukaryotic cells? • If you chose plant cells, how are chloroplasts replicated within plant cells? How are these processes similar to microbes? • Do endosymbotic relationships still exist today? • What are the advantages and disadvantages of such relationships?

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? - Answer-They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin - Answer-Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall - Answer-You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function - Answer-Involved in intr...

The ecology of algae in aquatic ecosystems parallels that of plants in terrestrial ecosystems. Make three points to support this statement. - Aglae and mosses/plants have similar features such as: - branched apical growth - cuticles - asymmetrical flagellated cells - cellulose, thylakoids, chlorophyll b, some have 2 flagella... If some Euglenoids have the same pigment as green algae and higher plants, why are they not so closely related? - secondary endosymbiosis Why evolve towards a s...
