You receive a sample slide of an organism while observing it under a microscope you know the organism is single celled and green in color. There are multiple individual organisms on the slide. Based on this initial information you can guess that it it is either a bacterium or a protist. Which trait is least likely to help you identify the correct group of this organism

The trait that is least likely to help identify the correct group of this organism is its green color. While green coloration may indicate the presence of chlorophyll for photosynthesis, there are both bacteria (such as cyanobacteria) and protists (such as algae) that can be green in color. Other characteristics, such as cell shape, size, and specific structures, would be more useful in determining whether the organism is a bacterium or a protist.
