Can you describe a major innovation in body plan that first occured in roundworms?
A major innovation in the body plan of roundworms (nematodes) is the development of a pseudocoelom, a fluid-filled body cavity that lies between the endoderm and mesoderm. This structure provides structural support and allows for greater flexibility and movement, facilitating more efficient nutrient distribution and waste removal. The pseudocoelom also plays a crucial role in the circulatory and digestive systems, distinguishing roundworms from more primitive organisms with solid body plans.
what is a roundworms body shape?
cylinderical
Roundworms have muscle tissue and a gut with one opening?
Roundworms are multicellular organisms that possess longitudinal muscles and a complete digestive tract, with a mouth and an anus. Their body plan is characterized by a single body cavity that houses their organs, including their nervous and reproductive systems.

They get into your body through raw food.
Compare and contrast the body of a flatworm to the body plan of a roundworm?
Flatworms are considered acoelomate, since they have no body cavity, and roundworms are pseudocoelomate because they have a body cavity, but it is not derived from the splitting of the mesoderm tissue. Also, flatworms only have one opening in their digestive system unlike roundworms with two.
What is the body structure of roundworms?
Roundworms have long, cylindrical bodies that taper at both ends. They have a complete digestive system with a mouth and an anus, and their bodies are covered in a protective cuticle. Roundworms also have a fluid-filled body cavity called a pseudocoelom.
