The cells in the sponge that have a flagella and create the current of water that flows through the sponge are called Collar Cells.
1. Collar Cells: These cells, also known as choanocytes, have a flagellum that beats to create water currents. The flagellum helps in moving water through the sponge, bringing in nutrients and oxygen while removing waste products.
By creating these water currents, collar cells play a crucial role in the sponge's feeding and respiration processes. This movement of water also aids in reproduction and maintaining the overall health of the sponge.
