An image shows a cell with a nucleus and membrane-bound organelles; which category would this most likely be?

• A. Plant cell
• B. Animal cell
• C. Bacterial cell
• D. Fungal cell

Answer: (B)

Cells with a nucleus and membrane-bound organelles are eukaryotic, which includes plants, animals, and fungi. Bacteria, on the other hand, are prokaryotic and lack a true nucleus and membrane-bound organelles. To narrow it down among the eukaryotes, consider typical features: plant cells usually have a rigid cellulose cell wall and chloroplasts for photosynthesis, while fungal cells have cell walls made of chitin. Animal cells generally lack a cell wall and chloroplasts. If the image shows a cell that has a nucleus and organelles but does not display a cell wall or chloroplasts, it fits best with an animal cell. Therefore, the category is animal cell.
