Some scientists think that complex eukaryotic cells formed from the union of two separate prokaryotic cells. The engulfing of one prokaryotic cell by another is a plausible explanation of why

a
eukaryotic cells don't share any similarities with prokaryotic cells.
b
organelles in a eukaryotic cell work cooperatively.
c
eukaryotic cells lack the defense mechanisms of prokaryotic cells.
d
organelles in a eukaryotic cell would attack other cells.

Answer 1

The best answer to the question is:

**b** organelles in a eukaryotic cell work cooperatively.

This option aligns with the theory of endosymbiosis, which suggests that eukaryotic cells evolved from the engulfing of one prokaryotic cell by another. This symbiotic relationship allowed the engulfed prokaryotic cell to become an organelle (such as mitochondria or chloroplasts) that works cooperatively with the host cell, contributing essential functions that benefit the overall cell.
