Detailed explanation-1: -The Kingdom Protista is a large, diverse collection of eukaryotic organisms. This heterogeneous Kingdom is referred to as the ‘junk drawer’ Kingdom because organisms that do not belong in the other eukaryotic Kingdoms (Plants, Fungi, Animals) are placed here (similar to objects in in a junk drawer that have no home).

Detailed explanation-2: -These unique organisms can be so different from each other that sometimes Protista is called the “junk drawer” kingdom. Just like a junk drawer, which contains items that don’t fit into any other category, this kingdom contains the eukaryotes that cannot be put into any other kingdom.

Detailed explanation-3: -Anderson (in the Bozeman Science video on Protists) call the group “Protists” the “Biological junk drawer"? Because Protists are not important biologically. Because Protists are a group of organisms that aren’t all very closely related to each other.

Detailed explanation-4: -Protista includes many kinds of unicellular eukaryotic organisms. Some of these organisms use appendages, such as hair-like cilia or whip-like flagella for moving around. Their mode of nutrition can be autotrophic or heterotrophic. Examples are unicellular algae, diatoms and protozoans.
