The presence of which organelle indicates that eukaryotic cells have evolved from prokaryotic cells? A) Membrane-bound Nucleus B) Plasma Membrane C) Endoplasmic Reticulum @Compassionate @Somy Correct answer gets a medal .

OpenStudy (somy):

what do u think?

OpenStudy (anonymous):

I was thinking B) Plasma Membrane .

OpenStudy (somy):

OpenStudy (anonymous):

OpenStudy (somy):

@Abhisar

OpenStudy (anonymous):

I need help !

OpenStudy (somy):

u r pretty much right i think

OpenStudy (anonymous):

Ok . . .

OpenStudy (somy):

because A and C are in Eukaryotes only

OpenStudy (anonymous):

It was wrong . . .

OpenStudy (somy):

ughh i guess it was supposed to be A sorry i wasn't as confident with A

OpenStudy (anonymous):

Its alright ^

OpenStudy (abhisar):

Eukaryotes have a primitive nucleus which lacks a nuclear membrane. Prokaryotes have a true nucleus which is bound by nuclear membrane. Now this suggests that prokaryotes are evolved from eukaryotes.

OpenStudy (abhisar):

Simplicity to complexity generally reflects evolution (except retrogressive evolution). Having a membrane bound nucleus makes it much more complex than eukaryotic non-membrane bound nucleus. This suggests that prokaryotes are evolved from eukaryotes. Apart from this membrane bound organales like mitochondria also support this kind of evolution.

OpenStudy (somy):

@Abhisar prokaryotes are evolved from eukaryotes => its opposite way round

OpenStudy (abhisar):

I didn't got u @Somy ! hv i done any mistake ?

OpenStudy (abhisar):
