Question

prokaryotes vs. eukaryotes
read each statement below and decide if describing prokaryotes, eukaryotes, or both. select one letter for each.

1. has a nucleus
2. has a cell membrane
3. bacteria
4. contains dna
5. always unicellular
6. plants
7. doesnt have a nucleus
8. can be unicellular or multicellular
9. has a cytoplasm
10. animals
11. dna is circular.
12. contains membrane - bound organelles
13. fungi
14. dna is linear.
15. has ribosomes

look at the cells below. label the prokaryotic cell and the eukaryotic cell. label the cell membrane, cytoplasm, dna, and ribosome in each.

Explanation:

Prokaryotes lack a nucleus and membrane - bound organelles, are often unicellular, and have circular DNA. Eukaryotes have a nucleus, membrane - bound organelles, and can be unicellular or multicellular with linear DNA. Both have cell membranes, cytoplasm, DNA, and ribosomes. Plants, animals, and fungi are eukaryotes, while bacteria are prokaryotes.

1. Eukaryotes have a nucleus.
2. Both have a cell membrane.
3. Bacteria are prokaryotes.
4. Both contain DNA.
5. Prokaryotes are always unicellular.
6. Plants are eukaryotes.
7. Prokaryotes don't have a nucleus.
8. Eukaryotes can be unicellular or multicellular.
9. Both have a cytoplasm.
10. Animals are eukaryotes.
11. Prokaryotes' DNA is circular.
12. Eukaryotes contain membrane - bound organelles.
13. Fungi are eukaryotes.
14. Eukaryotes' DNA is linear.
15. Both have ribosomes.

For the cell diagrams: The cell on the left with a clearly defined nucleus and membrane - bound organelles is the eukaryotic cell. Label the outer boundary as the cell membrane, the jelly - like substance inside as cytoplasm, the structure in the nucleus as DNA, and the small dots as ribosomes. The cell on the right without a defined nucleus and membrane - bound organelles is the prokaryotic cell. Label the outer boundary as the cell membrane, the inner substance as cytoplasm, the coiled - up region as DNA, and the small dots as ribosomes.

Answer:

1. Eukaryotes
2. Both
3. Prokaryotes
4. Both
5. Prokaryotes
6. Eukaryotes
7. Prokaryotes
8. Eukaryotes
9. Both
10. Eukaryotes
11. Prokaryotes
12. Eukaryotes
13. Eukaryotes
14. Eukaryotes
15. Both

Left cell: Eukaryotic cell. Right cell: Prokaryotic cell.
