Detailed explanation-1: -All protists are eukaryotic organisms. This means that they have a membrane-enclosed nucleus and other cell organelles. Most protists are aquatic, others are found in moist and damp environments. Most are unicellular, however, there are a few multicellular protists such as the giant kelp.

Detailed explanation-2: -Protists are a taxonomically inhomogeneous group of mostly unicellular eukaryotic microorganisms.

Detailed explanation-3: -Protists are eukaryotes as they possess a nucleus and other membrane-bound organelles (structures that perform a specific job). At one time, simple organisms such as amoebas and single-celled algae were classified together in a single taxonomic category: the kingdom Protista.

Detailed explanation-4: -Protists consist of both unicellular and multicellular organisms which have a nucleus and membrane-bound organelles. Therefore, protists are eukaryotic, rather than prokaryotic.

Detailed explanation-5: -Although the majority of protists are unicellular, some are multicellular organisms. One notable example is the giant kelp, which is a type of brown algae and can reach lengths of up to 65m (215 feet). Other examples of multicellular protists include seaweeds, such as red algae and green algae.
