Quizplus · Accepted Answer

The kingdom Protista includes a diverse group of organisms that do not fit clearly into any other kingdoms. Protists can have animal-like characteristics such as being motile and heterotrophic, or they can have plant-like characteristics such as being photosynthetic. This diversity and lack of clear defining features can make it difficult to classify protists and to determine their relationships to other kingdoms.
