To see the stereo effect, please gaze at infinity at a point between the two images. You should eventually see three images. The middle image will be a combination of the left and right images and it should look solid (stereo or 3d). The effect can sometimes be improved by holding a sheet of paper or card perpendicular to the image pair so that your left eye only sees the left image and your right eye only sees the right image. To focus, move your head closer to or further from the image. It might take a few tries to achieve the effect. Volvox is a freshwater alga that forms spherical colonies. Volvox is commonly studied in biology classes because it represents a possibly primordial organisational state between a colony and a multicellular organism. Volvox Structure: individual cells (reminiscent of Chlamydomonas) are oriented with their flagella radiating out from the colonial ball (you can see this as a sort of halo or fringe). In some types, cytoplasmic bridges connect the cells giving the sphere surface a reticulated appearance. Daughter colonies are seen inside the parent colony. |
