Answered

One theory that explains the origin of eukaryotic cells suggests that they resulted from large prokaryotic cells engulfing smaller prokaryotic cells. These smaller engulfed cells then contributed to the homeostatic needs of their new hosts.

Which observation supports this theory?

A. Mitochondria have their own DNA.
B. The endoplasmic reticulum is enclosed by a membrane.
C. The plasma membrane consists of a phospholipid bilayer.
D. The arrangement of the parts of the cytoskeleton gives a cell its shape.

Final answer:

Mitochondria having their own DNA supports the theory of eukaryotic cells evolving from prokaryotic cells engulfing smaller cells.


Explanation:

One observation that supports the theory of eukaryotic cells evolving from prokaryotic cells engulfing smaller cells is that mitochondria have their own DNA. Mitochondria, which are organelles responsible for cellular respiration and ATP production, are believed to have originated from engulfed aerobic prokaryotes. The presence of their own DNA supports the theory that they were once independent prokaryotic cells.
