Study Notes
Sponge Cells and Structure
- Amoebocytes are responsible for producing a sponge's skeleton.
- Osculum is the name of the large opening through which water leaves the spongocoel in a sponge.
- Amoebocytes are totipotent, meaning they can transform into any other cell type required by the sponge.
- Choanocytes create water currents that draw food particles into the sponge.
- Porocytes surround the small pores (ostia) through which water enters a sponge.
- Spongin, a flexible protein fiber, is the composition of a sponge's skeletal system.
- Spongocoel is the central cavity of a sponge where flagellated choanocytes line the interior.
- Amoebocytes play various roles in sponges, including transporting food, producing reproductive cells, generating skeletal elements, and repairing injuries.
- Porocytes are the cells responsible for opening and closing to control water flow into a sponge through its pores.
- Spicules are needle-like structures found in a sponge's skeletal system, providing support and protection.
