Chlamydomonas, Chlorella, Amoeba and Paramecium belong to Kingdom Protista now. Earlier, Chlamydomonas and chlorella (possess cell wall) were placed under the category Algae in plant kingdom while Amoeba and Paramecium (lack cell wall) were placed under animal Kingdom. 
They are now grouped in the same kingdom as the criteria for the classification of 5 Kingdoms is different. They are unicellular eukaryotes and on this basis, they are now in the same kingdom.
