Question

A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?

Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

Answer 1

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic

Step-by-step explanation:

Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

-this is a plant cell because of the cell wall

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

-prokaryotes don't have DNA contained in a nuclear membrane

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

- DNA contained in a nuclear membrane --> eukaryototic

- cell wall --> plant cells, which are eukaryotic

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

-DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too
