What are the Ostia in a sponge?
Ostia are small pores found on the surface of a sponge that facilitate water flow into its body. They allow water, which carries oxygen and nutrients, to enter the sponge's internal cavity, where it is filtered for food particles. These openings are crucial for the sponge's filter-feeding mechanism, enabling it to sustain itself in its aquatic environment.
Are ostiums and pores the same?
No, ostiums and pores are not the same. Ostiums are small openings in the body, such as the entrance of a sponge's canal system, while pores are tiny openings in the skin or other surfaces that allow substances to pass through.
How do waste and oxygen move in and out of the cell in a sponge?
In sponges, waste and oxygen move in and out of cells primarily through a process called diffusion. Water is drawn into the sponge's body through small openings called ostia, allowing oxygen and nutrients to dissolve in the water and enter the cells. Simultaneously, waste products are expelled from the cells into the surrounding water, which is then expelled through larger openings called oscula. This continuous flow of water facilitates the exchange of gases and waste, sustaining the sponge's cellular functions.
