Because they are more different than they are alike.
Protista is the eukaryotic kingdom that is not monophyletic and may soon be split into several kingdoms due to its diverse and unrelated members. This is because genetic research has shown that the members of Protista are more closely related to other eukaryotic kingdoms than to each other.
The kingdoms that have members with cell walls are Fungi, Plantae, and some members of the kingdom Protista. In Fungi, the cell walls are primarily composed of chitin, while in Plantae, they are made of cellulose. Additionally, certain protists, such as algae, also possess cell walls, although their composition can vary. In contrast, the kingdom Animalia does not have cell walls.
Advances in systematics have caused the kingdom Protista to crumble. the former kingdom is paraphyletic: some protists are more closely related to plants, fungi, or animals than to other protists. {& plants are a problem: sister clade to "green algae" - but not included in "protists"} As a result, the kingdom Protista has been abandoned ... Biologists still use 'protist 'informally, {like 'reptile' or 'dog'} as a convenient way to refer to eukaryotes that are neither plants, animals, nor fungi.
The members of the kingdom Protista are least similar to other kingdoms like Plantae and Animalia because Protists are unicellular or simple multicellular organisms with diverse characteristics, while plants are multicellular and typically photosynthetic, and animals are multicellular and heterotrophic.
All protists havee nuclei and are unicellular.

Members of the kingdom Fungi are Heterotrophs and the Members of the kingdom Plantae are Photosynthetic Autotrophs.

In the five kingdom system, the three kingdoms that have organisms capable of photosynthesis are some bacteria (mainly cyanobacteria) in the Kingdom Monera, algae in the Kingdom Protista, and plants in the Kingdom Plantae.
All protists havee nuclei and are unicellular.

There is no single kingdom that is unicellular. All prokaryotes (organisms with no cell nucleus) are unicellular, and they belong to two domains, bacteria and archaea. Eukaryotes, or organisms with a cell nucleus, are divided into four kingdoms, plants, fungi, animals, and protists (although recently scientists began to reclassify protists into multiple separate kingdoms). In each of the fungi and protist kingdoms, there are a variety of members that are unicellular, and also some members that are multicellular. Animals and plants are always multicellular (except possibly one animal group called Myxozoa).
