Porifera Body Structure
Asked by Mahek A · 2 years ago
How is the body structure of Porifera organized for water flow and feeding?
1 Answer
The body structure of Porifera is organized for efficient water flow and feeding:
1. Numerous small pores (ostia) on the body surface allow water to enter
2. Water flows through a system of canals lined with collar cells (choanocytes)
3. Choanocytes filter food particles from the water
4. Water exits through a large opening called the osculum
5. This water current system helps in feeding, respiration, and excretion
6. The body wall consists of two layers: pinacoderm (outer) and choanoderm (inner), with a gelatinous mesohyl in between
