How did the kingdom Protista come about?

The kingdom of protists was formed in water.

Explanation:

Members of this kingdom are generally equal and less involved in structure than other eukaryotes. In superficial terms, however, they have certain similarities with other eukaryotic groups, that is, animals, plants and fungi. These organisms are multicellular but mostly unicellular. The main characteristic of these organisms is that they have a defined cell nucleus. This trait makes them part of the realm of eukaryotic organisms, along with fungi, plants and animals.
