Volvox (Volvox sp.) is found in ponds and ditches. Up to 1000 single-celled green algae,each one with a tiny pair of whip-like tails,are linked together to form a hollow sphere. Inside this sphere you can see smaller daugther-colonies,which eventually come free when the original colony disintegrates. Volvox is more like a multicellular organism than a colony of single cells. It displays already the two essential features of a multicellular organism: the cells become specialised and they cooperate. Magnification: 60x at 5'x7' | |
