Which is bigger bacteria or protist?

Answer 1

eukaryotic cells first came about is called the endosymbiotic theory

This is wrong. Prokaryotic cells come first. The endosymbiotic theory is the hypothesis that sometime in history one bacteria 'ate' another bacteria (phagocytosis) and didn't completely digest its meal. What was left has become the modern day mitochondria in animal cells and the chloroplast and mitochondria in plant cells. Or more simply two prokaryotic cells formed a symbiotic relationship. But over time one organism gained the upper hand as their is genetic evidence for DNA transfer from the plastid in the organelle to the DNA in the nucleus.

Answer 2

It is not known which came first..scientists are still trying to figure this out. Archaebacteria "the ancient ones" are called this because they live in extreme environments similar to environments when the earth was first created. However, it is still not known which came first because Archaea, Eubacteria, and Eukaryotes are all so distinct from one another.
