Are cyanobacteria protist Why or why not?

Protista is a kingdom of misfits. It includes a wide variety of microscopic life that doesn't fall into any of the other kingdoms. There are plant-like protists, animal-like protists and even fungus-like protists. They are all eukaryotic, meaning that they have a distinct nucleus and complex organelles within their cells, such as mitochondria and Golgi bodies. So, yes, they are since they do not fit in any other classification.
