5. Clem is developing a model of a cell. He labels a central structure as the nucleus and writes a caption describing how DNA is kept inside the nucleus. Which is an important condition of Clem's model?

A. The model describes eukaryotic cells, but not prokaryotic cells.
B. The model describes animal cells, but not plant cells.
C. The model describes plant cells, but not animal cells.
D. The model describes a cell of a unicellular organism, but not a multicellular organism.

Answer :

The important condition of Clem's model is A. The model describes eukaryotic cells, but not prokaryotic cells.

Which is an important condition of Clem's model?

Clem's model is likely representing eukaryotic cells because prokaryotic cells lack a true nucleus. In eukaryotic cells, the DNA is housed within the nucleus, separated from the cytoplasm by a nuclear membrane. Prokaryotic cells, on the other hand, have a nucleoid region where the genetic material is found but lack a membrane-bound nucleus.

Therefore, the essential condition for Clem's model is that it pertains to eukaryotic cells, ensuring a clear distinction between the nucleus-containing eukaryotic cells and the nucleus-lacking prokaryotic cells.

Final answer:

Clem's model describes eukaryotic cells, but not prokaryotic cells, which do not have a defined nucleus. His model could apply to either plant or animal cells and to both unicellular and multicellular organisms, as all of these can be eukaryotic.

Explanation:

The important condition of Clem's model, which labels a central structure as the 'nucleus' storing DNA, is that The model describes eukaryotic cells, but not prokaryotic cells. This is because the presence of a nucleus with enclosed DNA is a distinguishing characteristic of eukaryotic cells. Prokaryotic cells, on the other hand, have their DNA floating freely in the cytoplasm and lack a defined nucleus. It's important to note that both plant and animal cells can be eukaryotic, as can cells of some unicellular and multicellular organisms. This means that option A, which says the model describes eukaryotic cells but not prokaryotic cells, is correct. Eukaryotic cells are found in plants, animals, fungi, and protists. Therefore, options B, C, and D are incorrect.
