How does an organ molecule pass into a sponges cell?

In sponges, organ molecules pass into cells primarily through a process called phagocytosis. Specialized cells called choanocytes create water currents that draw in food particles and organic molecules. Once inside, the choanocytes engulf these particles, enclosing them in a food vacuole, where digestion occurs. This efficient system allows sponges to obtain nutrients directly from their environment.
