2. Identify the cells below by using the terms eukaryote and prokaryote.

Cell Y _____________________________

Cell X_________________________

3. What is the advantage that prokaryotic cells have for being more simple than eukaryotic cells?

4. Use the word bank to place the characteristics under the appropriate cell type.

Word Bank Prokaryotic Cell Eukaryotic Cell

5. A theory that describes the difference in cellular complexity suggests that two prokaryotic cells lived together in a symbiotic relationship in which one lived within the other, and these eventually gave rise to eukaryotic cells with chloroplasts and mitochondria. What is the name of this theory? ___________________________________

16. Iodine turns blue-black in the presence of starch. Starch solution is placed inside a semipermeable dialysis sac (balloon/membrane). The sac is placed in a solution of water and iodine. The sac (membrane) is permeable to water and iodine, but not to starch.
