The organ in Euglena that is sensitive to light is called the "eye spot." This is a small, oval-shaped structure located near the base of the flagellum. The eye spot contains a pigment called "stigma" which is sensitive to light. This helps Euglena to detect changes in light intensity and to move towards or away from light sources, allowing it to carry out photosynthesis efficiently.
