Question

What is the main difference between the two hypotheses for the origin of the eukaryotic cell?

Answer 1

The main difference between the two hypotheses for the origin of the eukaryotic cell is whether the nucleus appear before or after the endosymbiotic event

Step-by-step explanation:

There are two major hypothesis for the origin of eukaryotic cell (cell withe the membrane-bound organelles and nucleus):

1. Hypothesis 1 or Archaezoan hypothesis- this hypothesis suggest that the eukaryotes with nucleus appeared prior to the endosymbiotic events
2. Hypothesis 2 or Symbiotic hypothesis- this hypothesis suggest that endosymbiotic event lead to the formation of eukaryotic cell (prokaryotic cell engulfed other prokaryotes aerobic bacteria, which became mitochondrion/chloroplast) but that nucleus was formed after the event.
