If body of any animal is cut through ______ axis of body, it may or may not produce two equal halves. Depending upon this property, there are different types of animal bodies. In the case of ______ body, there is no any such imaginary axis of the body through which we can get two equal halves. For example Amoeba, ______ some sponges. In radial symmetry type of body, if imaginary cut passes through central axis but any plane of body, it gives two ______ halves. For example Starfish. In case of this animal, there are five different planes passing through ______ axis of body through which we can get two equal halves. In Bilateral symmetry type of body, there is only one such imaginary axis of body through which we can get two equal halves. For example: ______ fishes, frog, birds, human, etc.
