Norman believes that infants are prokaryotes because they seem too incompetent to contain a nucleus. According to him, “Babies have smaller brains so it only makes sense that they don’t have enclosed nuclei. They become eukaryotes once they reach 14 months. Who is the genius now!!”

You’re wrong Norman! That’s why you shouldn’t have skipped biology in third period! You’ll be working at a gas station with that idiocy, that’s all I know!

Norman is incorrect because brain development does not impact an organism’s cellular composition. Prokaryotes are organisms whose cells do not have an enclosed nucleus. Bacteria is an example of this. Babies are not.

Norman’s belief is correct because brain development does impact an organism’s cellular composition. Because infant brains are still heavily developing, their brain tissue contains free floating genetic material. When they reach fourteen months of age, their brains (although not fully formed as that occurs in a person’s 20s) will have formed a nucleus to encase that material.

Norman is incorrect because a cell is characterized by the presence of a nucleus and other membrane-bound organelles.
