Question

the table shows the structures found in an unknown cell and the percent of the total cell mass each structure comprises. based on the information provided, what can be concluded about the unknown cell? since the cell lacks a cell wall, it must be a plant cell. since the cell lacks chloroplasts, it cannot be a prokaryotic cell. since the cell has mitochondria and dna, it must be a eukaryotic cell. since the cell has a cell membrane and dna, it cannot be an animal cell.

Explanation:

Plant cells have cell walls, so a cell lacking a cell - wall cannot be a plant cell. Prokaryotic cells lack chloroplasts, so the absence of chloroplasts does not rule out a prokaryotic cell. Eukaryotic cells have membrane - bound organelles like mitochondria and DNA enclosed in a nucleus. Having mitochondria and DNA indicates that the cell is eukaryotic. Animal cells have a cell membrane and DNA, so having these does not rule out an animal cell.

Answer:

Since the cell has mitochondria and DNA, it must be a eukaryotic cell.
