Sponges get food by straining the water that comes through their pores. All animals need food, water, and oxygen to survive. Do sponges drink water?īut sponges are animals because they must take in food, and they are multicellular. They whip their flagella constantly to create a current which pulls water into the sponge through the pore cells.

The inner body wall consists of choanocytes (collar cells). Water enters the sponge through the pore cells. How does water move through a sponge quizlet? Cells in the sponge walls filter food from the water as the water is pumped through the body and the osculum (“little mouth”). Instead of a mouths they have tiny pores (ostia) in their outer walls through which water is drawn.

Sponges have a unique feeding system among animals. How does water and food move through a sponge body?

Water enters very small pores found among the cells (pinacocytes), which line the outer surface of the sponge.

The chambers, scattered throughout the body of the sponge, have pores through which water passes into a complex system of incurrent canals, then into a spongocoel (internal cavity) by way of excurrent canals.
