Question

The true coelom is a space between the body wall and the alimentary canal. It is lined by

• A. mesoderm on one side and ectoderm on the other side
• B. endoderm on one side and ectoderm on the other side
• C. mesoderm on both the sides
• D. ectoderm on both the sides

Answer 1

The correct option is C mesoderm on both the sides

Coelomate animals or Coelomata ("true coelom") have a body cavity called a coelom with a complete lining called peritoneum derived from mesoderm (one of the three primary tissue layers). The complete mesoderm lining on both sides allows organs to be attached so that they can be suspended in a particular order while still being able to move freely within the cavity.
