Bilateral and Radial Symmetry in Animals (Classification On the Basis of Body plan)

PoWer Of KnOwledge Academy・6 minutes read

Animals are classified based on symmetry into radial symmetry, bilateral symmetry, and asymmetry, with examples like jellyfish, humans, and sponges respectively. Radial symmetry allows for division at multiple places, bilateral symmetry at one specific place, while asymmetry shows no equal halves regardless of cutting location.

Insights

  • Animals are classified based on symmetry into three main types: radial symmetry, bilateral symmetry, and asymmetry.
  • Radial symmetry allows animals to be divided into two equal halves at multiple points, bilateral symmetry at one specific point, and asymmetry shows no symmetry at all.

Animal Classification Based on Symmetry Types

  • Animals are classified based on symmetry, with three main types: radial symmetry, bilateral symmetry, and asymmetry.
  • Radial symmetry refers to animals that can be divided into two equal halves by cutting them at multiple places, like jellyfish or starfish.
  • Bilateral symmetry includes animals like humans, which can only be divided into two equal halves by cutting them at one specific place.
  • Animals with asymmetry, like sponges, cannot be divided into two equal halves regardless of where they are cut, showcasing no symmetry at all.
