A plant-like feature in Euglena is the presence of a pigment spot, also called an eyespot or stigma. This is a small, colored organelle located near the base of the flagellum (a long, whip-like structure that helps Euglena move). The pigment spot contains a light-sensitive pigment that helps Euglena detect and move towards light, which is important for photosynthesis. While Euglena is a unicellular organism, it has features of both plants and animals. The pellicle is a proteinaceous layer that covers and supports the cell membrane, the gullet is a feeding structure found in some protozoa, and the large spot is not a known feature of Euglena.
