4. Body Plans Body Plans Animals that are irregular in shape are asymmetrical. Animals that are irregular in shape are asymmetrical. Animals that are regular in shape are symmetrical. Animals that are regular in shape are symmetrical.

5. Body Plans Body Plans An animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. An animal has radial symmetry if it can be divided along any plane, through a central axis, into equal halves. An animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other. An animal has bilateral symmetry if it can be divided down its length into similar right and left halves forming mirror images of each other.

6. Which figure has bilateral symmetry? Which has radial symmetry?

7. Protection and Support Protection and Support Though not all animals have a skeleton, those that do can be divided into two groups: Though not all animals have a skeleton, those that do can be divided into two groups: –Those with an exoskeleton – a hard, waxy coating on the outside of the body that protects internal organs, provides a framework for support, and a place for muscle attachment. –Those with an endoskeleton – support framework within the body that protects some organs and a brace for muscles to pull against.
