Answer 2

BODY SYMMETRY -

• Body symmetry is the balanced distribution of duplicate body parts.
• Organisms can be divided into three categories based on body symmetry as -

1. Asymmetry

• Animals with no or disproportionate body plan.
• Example - Porifera, Flounder fish.

2. Radial symmetry

• The body parts are along the central axis.
• The two halves formed along the axis are mirror images of each other.
• The two parts are described as one side having a mouth and the other is without the mouth.
• Example - Sea anemone, Ctenophores.

3. Bilateral symmetry

• Body division in two halves along the sagittal plane.
• The symmetry has head and tail with dorsal and ventral side and front and backside.
• The organisms have organised nervous system at the anterior end leading to the cephalization.
• Example - Butterfly, Echinodermata.
