How are flagellates different from euglena green?

Euglena green are unicellular eukaryotes that have the characteristics of both plant and animal cells. Like plant cells, some species are photoautotrophs and have the ability to use light to obtain nutrients through photosynthesis. Like animal cells, other species are heterotrophs and acquire nutrition from the environment by feeding on other organisms.
Flagellates are cells or unicellular organisms that move with the help of flagella. Flagella are whip-like appendages that can move an organism or a cell.
