Solution:

All single-celled eukaryotes are placed under Protista, but the boundaries of this kingdom are not well-defined. What may be 'a photosynthetic protistan' to one biologist may be 'a plant' to others. Chrysophytes, dinoflagellates, euglenoids, slime moulds and protozoans are included under Protista. Members of Protista are primarily aquatic. Diatoms are chief producers of the ocean, and dinoflagellates are known to release some toxic substances.
