Flagellum

Summary: Euglenas have an eye spot to sense Light. They also have a flagellum. This is like a tail. By moving the flagellum, the euglena can ‘swim’ towards the light to photosynthesize. This allows the euglena to make as much food as possible. Tags: science student-book-7 biology Created: 2026-05-21 Last Updated: 2026-05-21
