The image shows a close up of a plant cell on a white surface, with text at the bottom left corner. It appears to be a photo of a rotifer, a type of algae, with its long, thin, oval-shaped body and thin legs. Its color is a light greenish-brown color and its fins are a darker shade of green. Its eyes are large and round, and its mouth is slightly open, revealing its small, pointed teeth.
