Characteristics of Protists. Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. Kelp, or 'seaweed,' is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems.
Monera 

These organisms are the simplest prokaryotic cell structures. 
The Monera cell structure lacks nuclei and many other cell organelles. 
The source of nutrition for these organisms is usually photosynthesis or chemosynthesis. 
These organisms are the simplest prokaryotic cell structures. 

Protista 

They are eukaryotic, meaning they are not bacterias and contain a true nucleus. 
They can be multicellular or unicellular. 
Some are heterotrophic, others are autotrophic. 
Some reproduces sexually and some reproduces asexually. Still others utilize both methods, asexual reproduction inside a host organism and sexual reproduction outside. 
Many are parasitic and lives in ponds
