Final answer:
Vertebrates have a backbone, while invertebrates do not. Vertebrates include mammals, birds, reptiles, amphibians, and fish, while invertebrates encompass a wide range of animals including insects, spiders, worms, mollusks, and jellyfish.
Step-by-step explanation:
The main difference between a vertebrate and an invertebrate body plan lies in the presence or absence of a backbone or vertebral column. Vertebrates have a well-developed backbone, which provides structural support and protects the spinal cord. Examples of vertebrates include mammals, birds, reptiles, amphibians, and fish. On the other hand, invertebrates lack a backbone and have a diverse range of body plans, such as insects, spiders, worms, mollusks, and jellyfish.
