pore cells
the sponge absorbs water, and keeps it in. if you rotate or tilt it, the water will move because of gravity.
The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
No in fact they have multiple openings called pores, which allow water and nutrients to flow in and out of the sponge
"clean" water and "waste" water in a sponge are all the same. Their bodies allow constant flow of water, there is no beginning and end to a sponge; thus technically waste water leaves a sponges body through its many pores.
Flow is a verb and a noun. Verb: Water flows from the faucet. Noun: The steady flow of water from the fountain is relaxing.
Facts From : Staight a student ok here are the answers....System TypeSponges SystemMuscular-SkeletalA sponge is a hollow tube with many pores or openings. The skeleton is made of lime or silicon.DigestionA sponge takes in food via the water that flows through the pores.NervousA sponge has a very low level reaction to the world around it and does not have a brain per se.CirculationA sponge has water flow in through the pores. The water contains the food and oxygen the sponge needs.RespirationA sponge takes in water through its pores and in more advanced forms, with canals that move the water to all throughout the sponge. Then the oxygen from the water is used.ReproductionA sponge reproduces by budding and also sexually.ExcretionA sponge has carbon dioxide and other wastes removed as the water moves in and out through the pores.SymmetryA sponge has either radial symmetry or is asymmetrical.ColorationA sponge is white, red, orange, green, yellow, brown, purple, black (colors)
When a sponge is submerged in water, the water enters the sponge through the tiny holes in the sponge. The sponge fills up with water, as a balloon fills with air, only not as visibly. When you squeeze the sponge, the water exits that sponge through the tiny holes...exactly the opposite of how it entered! Tada! :)
a sponge holds water because of its holes
