Animal that have their body cavity filled with parenchyma are:
Correct answer: A. Acoelomates
- A. Acoelomates
- B. Pseudococlomates
- C. Coelomates
- D. Mesoderms
Explanation
Animals that have their body cavity filled with parenchyma are called "acoelomates." Parenchyma refers to the tissue that fills the space between the gut (digestive cavity) and the body wall in acoelomate animals. Unlike coelomates and pseudocoelomates, acoelomates lack a fluid-filled body cavity known as a coelom.
