Distinguish between intracellular and extracellular digestion?
Intracellular digestion takes place inside the cells by cellular enzymes, which are secreted by the surrounding cytoplasm into the food vacuole and the digestive products are then diffused in cytoplasm. It mainly occurs in unicellular organism and also is a less efficient method. Extracellular digestion occurs with the help of digestive enzymes poured into gastrovascular cavity by secretory cells and then the digestive products are diffused across the intestinal wall into various parts of the body. It mainly occurs in multicellular organisms and is more efficient.
