23. Euglena are unicellular organisms that can move around using a
flagellum. Though most are photoautotrophic, and all have membrane-
bound organelles, some may also eat other organisms for energy or
nutrients. They are most commonly found living in water, where they
often swim around to move towards better sources of light. (4 points)
