The sponge uses the choanocytes to move a steady current through its body.
The surface of the orange puffball sponge is covered with small pores that filter small particles of food from the water that passes through them. Each sponge has flagella that help move the water through the 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.
the sponge absorbs water, and keeps it in. if you rotate or tilt it, the water will move because of gravity.
help move water through the organism's body.
Choanocytes
Sponges respire through simple diffusion of gases across their body surface. They do not have specialized respiratory organs like lungs or gills. Oxygen from the water is absorbed directly into their cells, while carbon dioxide produced by cellular metabolism is released back into the surrounding water.
Little whips are flagella that help pump water through the pores for food.
The black ball sponge, also known as the "black ball sponge" or "Haliclona sp.", moves primarily through the flow of water around it rather than active movement. It relies on water currents to bring in nutrients and oxygen, while its porous body allows for water to flow through its structure. This passive movement enables it to filter feed, capturing small organic particles. Additionally, sponges can contract their body slightly to regulate water flow, but they do not have muscles or limbs for active locomotion.
Probably a sponge.
When you swim, water enters your body through your mouth and nose as you breathe and move through the water.
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)
The hair-like structures on a sponge cell that move back and forth to help move water or nutrients or waste through the canal are called flagella. These structures create a current that allows for the circulation of water and the uptake of nutrients in sponges.
