question 1 / 10
how does a eukaryotic organism differ from a prokaryotic organism?
a. a eukaryotic organism has nuclei, while a prokaryotic organism does not.
b. a eukaryotic organism is made up of cells, while a prokaryotic organism is not.
c. a eukaryotic organism contains genetic information, while a prokaryotic organism does not.
d. a eukaryotic organism is always made up of one cell, while a prokaryotic organism has many cells.

Explanation:

• Option A: Eukaryotic organisms have nuclei (membrane - bound organelles that house DNA), while prokaryotic organisms lack a true nucleus. Their DNA is in the nucleoid region (not membrane - bound).
• Option B: Both prokaryotic and eukaryotic organisms are made up of cells. Prokaryotes are single - celled, and eukaryotes can be single - celled (e.g., yeast) or multicellular.
• Option C: Both prokaryotic and eukaryotic organisms contain genetic information. In prokaryotes, it is usually in the form of a circular DNA molecule, and in eukaryotes, it is in linear chromosomes within the nucleus (and also in mitochondria and chloroplasts in some cases).
• Option D: Eukaryotic organisms can be single - celled (e.g., amoeba) or multicellular (e.g., humans). Prokaryotic organisms are generally single - celled.

Answer:

A. A eukaryotic organism has nuclei, while a prokaryotic organism does not.
