WebThe flow of water is initiated through the coordinated beating of flagella. Once water enters the sponge through ostia (Figure 1), it passes through a canal system of lesser or greater complexity, depending on the species, until it reaches the choanocytes. Once at the choanocyte, bacteria are captured in the microvillar net and passed to ... WebChoanocytes have flagella that propel water through the body. Pinacocytes can transform into any cell type. Lophocytes secrete collagen. ... The collagen that is normally found in the mesohyl becomes the outer protective layer. In freshwater sponges, gemmules may survive hostile environmental conditions like changes in temperature and serve to ...
WebThe choanocytes are arranged in such a way that their collars are oriented towards the apopyles. The flagella of the choanocytes are flexible with slight stiffness at the base. As a result the flagella beat from base to tip creating a water current in the same direction and drive the water from the flagellated chambers to the spongocoel. WebChoanocyte is a flagellated cell with a collar of protoplasm at the base of the flagellum, and which line the internal chambers of sponges. Hence the correct option is C. Was this …
