Verified step by step guidance1
Understand that Euglena is a unicellular organism that can perform photosynthesis, similar to plants.
Recognize that the eye spot, also known as a stigma, is a specialized organelle found in Euglena.
The primary function of the eye spot is to detect light, which is crucial for the process of photosynthesis.
Photosynthesis requires light to convert carbon dioxide and water into glucose and oxygen, providing energy for the organism.
Therefore, the eye spot helps Euglena orient itself towards light sources, optimizing its ability to perform photosynthesis.
