A complex protist with many organelles. The paramecium shows many behavioral adaptations that make it interesting to observe with the microscope. The name Spirogyra comes from the chloroplasts that are easily visible in their spiral-ribbon like structures. To the left of the green algae is the middle section of a Star Diatom. The sharp edge of the diatom is formed from the glass like silicon dioxide test or shell.
Some energy storing oil droplets are visible in the center portion.
