Explanation

The movement found in unicellular organisms are ciliary, flagellar and amoeboid types, In multicellular animals also, phagocytes migrate through the tissues by amoeboid movements. Ciliary movements are seen in cells lining the upper repiratory tract, fallopian tubes and vasa efferentia of testes, etc. Mammalian sperms move into the female reproductive tract by the flagellar movements.
