Question

a student is looking at a cell under a microscope and sees a nucleus, ribosomes, chloroplast and cell wall. is this cell a prokaryotic or eukaryotic cell? how do you know? be sure to explain your reasoning. rubric: 5 points fully articulated response to all parts of the question including examples as needed. 3 points is mostly articulated with some explanation of reasoning. 1 point is partially answered with no explanation of reasoning.

Explanation:

Prokaryotic cells lack a true nucleus and membrane - bound organelles like chloroplasts. The cell observed has a nucleus and chloroplasts, which are characteristic of eukaryotic cells. Eukaryotic cells can have a cell wall (e.g., plant cells) and ribosomes are present in both prokaryotic and eukaryotic cells.

Answer:

This is a eukaryotic cell.
