Purpose of coelom: A) provide a space for internal organs to be stored and allowed to grow.
A coelom, also called body cavity, is filled with fluid and is lined with mesoderm tissues. It acts as a cushion for the internal organs of an organism. In worms, a coelom acts as its skeletal system and maintains pressure inside it to enable its muscles to work.
Coelomic fluid allows the internal organs to move freely and grow within the cavity. It also helps in the transport of gases, nutrients, and waste products between different parts of the body.
