Question
Pseudocoelomates are more advanced than acoelomates.
✓
Answer
Acoelomates do not have body cavity. Their body is solid and hence the movement of internal organs is restricted. Pseudocoelomates have pseudocoelomic fluid in the pseudocoelom. It acts as a hydrostatic skeleton and allows free movement of visceral organs and circulation of nutrients.
