I'm hoping you meant Protista. Kingdom protista is actually very diverse. They are a monophyletic group, meaning they are diverse. They are primarily unicellular, and pretty much tiny, usually microscopic. Some can perform photosynthesis, while are heterotrophs, having to eat like an animal. Hope that helps!

Protoctista are eukaryotic, meaning they have a true nucleus. Monera are prokaryotic, meaning they have no nucleus.
The kingdom Protista (also known as Protoctista) includes organisms such as Protozoa, Algae and Fungus.
Some protoctista have cell walls made of various materials, like cellulose or silica, while others do not have cell walls. The presence or absence of cell walls in protoctista can vary depending on the specific species.

Protoctista is an outdated biological kingdom that encompassed a wide variety of eukaryotic organisms that did not fit into the plant, animal, or fungi kingdoms. It is no longer considered a valid taxonomic group due to advancements in molecular biology and the understanding of phylogenetic relationships among eukaryotes.
Protoctista and prokaryotes both lack a true nucleus and membrane-bound organelles. They are both unicellular organisms, although some protoctista may be multicellular. Additionally, they can both be found in various environments and play important roles in ecosystems.
The term Protoctista is an outdated kingdom classification that encompassed various eukaryotic organisms that didn't fit neatly into other kingdoms such as animals, plants, or fungi. It has since been replaced by more specific and accurate classifications based on genetic and evolutionary relationships.

Protoctista Kingdom
Algea is classified into "Protista"(Protoctista) kingdom.
