WebThe choanocytes and the amoebocytes that are present in the canal system of the sponge helps in intracellular digestion where food particles are digested inside the cellular food vacuoles by means of various acidic and alkaline enzymes. That’s the holozoic type of nutrition which is seen in animals and not plants. WebThe amoebocytes (derived from stem-cell-like archaeocytes), are so named because they move throughout the mesohyl in an amoeba-like fashion. They have a variety of functions: In addition to delivering nutrients from choanocytes to other cells within the sponge, they also give rise to eggs for sexual reproduction.
