A scientist found a new species in a rain forest. The species was small and green in color. She examined one of its many cells and found that the cell had a nucleus but no cell wall. To which kingdom does this species most likely belong? plants, because it is green and small bacteria, because it is small and has a nucleus fungi, because it is green and has no cell wall animals, because it is multicellular with no cell wall

The most likely kingdom that this species belongs to is animals, because it is multicellular with no cell wall.

Based on the information provided, the species most likely belongs to the kingdom "Animals, because it is multicellular with no cell wall." This is because the species is described as multicellular (which excludes bacteria and fungi) and lacks a cell wall (which distinguishes it from plants).

To determine the most likely kingdom to which the newly discovered species belongs, we can analyze the given characteristics - being small and green in color, having a nucleus but no cell wall.

Based on the information provided, we can eliminate the options of bacteria and fungi. Bacteria are often small, but they lack a nucleus, whereas fungi typically possess cell walls.

Considering the remaining options - plants and animals - we can see that plants are characterized by their green coloration due to the presence of chloroplasts. Additionally, plant cells typically have both a nucleus and a cell wall, which is composed of cellulose.

On the other hand, animals are multicellular, like the described species, and their cells possess a nucleus. Importantly, animals lack a cell wall, which aligns with the characteristics of the discovered species.

Therefore, based on the given information, the species most likely belongs to the animal kingdom, because it is multicellular and lacks a cell wall.
