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

Answer:

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

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
