Botany - Animal Kingdom Question with Solution | TestHub

Molluscs are triploblastic, bilaterally symmetrical coelomates. In some Molluscs likePila, due to torsion during growth, the adults become asymmetrical. The coelom is greatly reduced. It is restricted to the pericardial cavity (space around the heart), and to small spaces within kidneys and gonads (testes and ovaries). Spaces amongst the viscera (soft organs) contain blood and form hemocoel. They have triploblastic body wall with outer ectoderm middle mesoderm and inner endoderm.
