Volvox algae. Close-up light microscopy footage of a freshwater green alga Volvox sp. colony, containing an asexual daughter colony (large green sphere). The colony is a hollow sphere made up from thousands of cells connected by cytoplasmic threads and arranged in a single layer. Each cell has two flagella, which point outwards, and are used for locomotion. Each cell also contains a chloroplast (small green spheres) and a red eyespot. | |
