Question

what do you mean by radial and bilateral symmetry class 9

Answer 1

1. Bilateral symmetry involves the division of the animal through a sagittal plane, resulting in two mirror-image, right and left halves, such as those of a butterfly, crab, or human body.

2.Radial symmetry is the arrangement of body parts around a central axis, like rays on a sun or pieces in a pie.

Hope it helps

Answer 2

Radial symmetry- if the imaginary cut passes through central axis but any plane of body,it gives two equal halves.Ex.starfish

Bilateral symmetry- there is only one such imagery axis of body through which we can get two equal halves .Ex.insects, fishes,birds,And humans.
