Does Euglena Have Mitochondria? I Know Most Of Them Have Chloroplasts, And That Supplies The The Euglena Cell With Energy, And If Euglena Does Have Mitochondria What Is It's Function? Please Answer This Question Thanks

Almost all eukaryotes have mitochondria, including the euglena.  Even things with chloroplasts use them.  That is because chloroplasts serve to capture the energy from sunlight and use it to make carbohydrates.  Just like cells without chloroplasts, though, a euglena can't use sugar directly to fuel its biological processes; it needs ATP.  In order to convert the chemical energy stored in sugar to ATP with optimal efficiency, a cell needs mitochondria. 

Euglena can both eat food as animals do and can photosynthesize, like plants.
