*In case you are wondering, this is not homework. I am studying for an upcoming test.



1) What is the difference and similarities between passive transport, facilitated transport, and active transport?



Is facilitated diffusion related to passive transport because they seem to somewhat similar? Having trouble with this.



2) What is the origin of membranous organelle and the Eukaryotic energy-converting organelles mitochondria and chloroplasts?



This seems to refer to the endosymbiosis and invagination theories but I am not sure.



Thanks! Best answer=10 points!
