Question

comparing cell types
anatomy of a cell
review the image of the cell. what type of cell is this? provide an explanation for your answer.
a it is a eukaryotic animal cell. it contains organelles excluding chloroplasts.
b it is a prokaryotic animal cell. it is rounded, has organelles and dna in a nucleus.
c it is a prokaryotic cell. it does not contain cellular organelles including a nucleus.
d it is a eukaryotic plant cell. it contains organelles and the shape indicates a plant cell.
compare the image of the bacterial cell with that of the original cell image.

Explanation:

• Option A: Eukaryotic cells have a nucleus and membrane - bound organelles. Animal cells do not have chloroplasts (which are present in plant cells). This option correctly identifies the cell as eukaryotic (due to the presence of a nucleus and organelles like mitochondria, endoplasmic reticulum etc.) and animal (lack of chloroplasts).
• Option B: Prokaryotic cells do not have a true nucleus (DNA is in the nucleoid region). So, a prokaryotic animal cell is a wrong concept as animals are made of eukaryotic cells.
• Option C: The cell in the image has organelles like mitochondria, endoplasmic reticulum and a nucleus. So, it is not a prokaryotic cell.
• Option D: Plant cells have a cell wall (which gives them a more rigid shape, often rectangular or square - like in many cases) and chloroplasts. The cell in the image does not have these features, so it is not a plant cell.

Answer:

A. It is a eukaryotic animal cell. It contains organelles excluding chloroplasts
