Study Notes
Characteristics of Acoelomates
- Phylum Platyhelminthes lacks a body cavity or coelom.
- Mesoderm forms a loose, cellular tissue called mesenchyma or parenchyma.
- Mesenchyma or parenchyma fills the space between the ectoderm and endoderm.
- This tissue forms a packing around the internal organs to support and protect them.
- Animals with this characteristic are called acoelomates.
