Question

for each statement listed below, decide if it best describes eukaryotic cells (e), prokaryotic cells (p), or both types of cells (b). 1) _ cells contain dna. 2) _ cells contain a nucleus. 3) _ cells contain a cell membrane. 4) _ existed 3 billion years ago. 5) _ existed 2 billion years ago. 6) _ about 0.5 μm in size. 7) _ plant and animal cells. 8) _ bacteria cells. 9) _ contains cytoplasm. 10) _ contains a cytoskeleton prokaryotic cells vs. eukaryotic cells how are they different? how are they alike? directions: using your notes from class, construct a venn diagram to show the similarities and differences among prokaryotic cells and eukaryotic cells. be sure each side is clearly labeled.

Explanation:

1. Both prokaryotic and eukaryotic cells contain DNA, so it's B.
2. Only eukaryotic cells have a nucleus, so it's E.
3. Both types of cells have a cell - membrane, so it's B.
4. Prokaryotic cells existed 3 billion years ago, so it's P.
5. Eukaryotic cells are thought to have existed 2 billion years ago, so it's E.
6. Prokaryotic cells are about 0.5 μm in size, so it's P.
7. Plant and animal cells are eukaryotic, so it's E.
8. Bacteria cells are prokaryotic, so it's P.
9. Both prokaryotic and eukaryotic cells contain cytoplasm, so it's B.
10. Only eukaryotic cells contain a cytoskeleton, so it's E.
