(i) Starfish
(ii) Gorilla
(iii) Paramecium

Open in App

Solution

A symmetry where any plane passing through the central axis divides the body into two equal halves is called the radial symmetry. Eg. Starfish. (1 Mark)

In bilateral symmetry, only a single plane divides the body into two equal halves. Eg. Gorilla. (1 Mark)

When no imaginary axis through body can get two equal halves, it is said to be asymmetrical. Eg. Paramecium. (1 Mark)
