Question

1. list the structure(s) that form the boundary between the inside and the outside of each cell in model 2.
2. what is different about the outermost boundary in a plant cell compared to an animal cell?
3. decide as a group whether the cells in model 1 or 2 are more complex and list at least three supporting reasons for your choice.

1. use the chart in model 3 to determine the meaning of the word prokaryote.
2. what does the word eukaryote mean?
3. based on the above word definitions, label the cells in model 1 and model 2 as prokaryotic or eukaryotic.
4. by comparing model 1 and model 2, what structures are the same in both prokaryotic and eukaryotic cells?
5. what differences are there between a prokaryotic and eukaryotic cell?

Explanation:

1. Cell - membrane forms cell boundary.
2. Plant cell has cell - wall outside membrane.
3. Prokaryote: before nucleus.
4. Eukaryote: true nucleus.
5. Common structures: cell - membrane, cytoplasm, ribosomes.
6. Prokaryotes lack nucleus and membrane - bound organelles.

Answer:

1. Cell membrane.
2. Plant cell has a cell - wall outside the cell membrane.
3. Organism without a true nucleus.
4. Organism with a true nucleus.
5. Cell membrane, cytoplasm, ribosomes.
6. Prokaryotes lack a nucleus and membrane - bound organelles; eukaryotes have them.
