Cell A stores DNA inside a nucleus. Cell B has circular DNA in the cytoplasm. Which statement is supported?
Prokaryotic and eukaryotic cells both make proteins. Which structure do both kinds of cells have for this job?
Both cells in the diagram have a nucleus, so both are eukaryotic. Which structure would you expect to find in both cells?
The diagram shows a bacterium. How does a typical bacterium compare in size with a typical human cheek cell?
In a model, a small cell has a membrane, cytoplasm, ribosomes, and a loop of DNA. What evidence best justifies prokaryotic classification?
A student model labels nucleus, mitochondria, and cell membrane in one cell. What evidence best supports calling the cell eukaryotic?
