Questions & Step-by-Step Solutions
What type of symmetry do most echinoderms exhibit?
Step 1: Understand what echinoderms are. They are a group of marine animals that include starfish, sea urchins, and sea cucumbers.
Step 2: Learn about symmetry. Symmetry refers to how the body of an organism is arranged.
Step 3: Identify the types of symmetry. The main types are bilateral symmetry (divided into two equal halves) and radial symmetry (arranged around a central point).
Step 4: Focus on adult echinoderms. Most adult echinoderms have a body plan that allows them to be divided into similar parts around a central axis.
Step 5: Conclude that most echinoderms exhibit radial symmetry, which helps them interact with their environment from all sides.
