The first description is Domain Eukarya, and Phylum Unikonta. This group includes organisms with a single flagellum or no flagella as seen in Ameba. Some members have animal and some have fungal characteristics. The second description sounds much like a Euglena.These are in Domain Eukarya and Phylum Euglenozoa. They are flagellated protozoans. Many are free-living and some are parasitic. However, euglena possess two flagella and have chlrophyll, thus can produce food by photosynthesis. Some can also absorb nutrients in order to feed.
