Question

You receive a sample slide of an organism. While observing it under a microscope, you notice that the organism is single-celled and green in color. There are multiple individual organisms on the slide. Based on this initial information, you guess that it is either a bacterium or a protist. Which trait is least likely to help you identify the correct group of this organism? (1 point) Responses the presence of different cell shapes the presence of different cell shapes the absence of a nucleus the absence of a nucleus the absence of cell structure membranes the absence of cell structure membranes the presence of cell structures in the cell the presence of cell structures in the cell

Answer 1

To distinguish between a bacterium and a protist, the trait that is least likely to help you identify the correct group of the organism is the presence of cell structures in the cell.

Bacteria (which are prokaryotic) and protists (which are eukaryotic) can both have various cell structures, but the distinguishing feature is the presence or absence of a nucleus: protists have a nucleus while bacteria do not. The other options, such as the presence of different cell shapes or the absence of cell structure membranes, would provide more relevant information for distinguishing between the two groups.
