Question

Cite a case of intracellular digestion in humans.

Answer 1

• In humans, the digestive tract mechanically and chemically breaks down food, so intestinal cells can absorb nutrients for the body.
  
• In the hydra, food is trapped in the gastrovascular cavity. Intracellular digestion takes place inside the cell.
  
• Intracellular digestion can also refer to the process in which animals that lack a digestive tract bring food items into the cell for the purposes of digestion for nutritional needs. This kind of intracellular digestion occurs in many unicellular protozoans, in some molluscs, Cnidaria and Porifera. Hence the statement for the case of intracellular digestions in humans is that the digestive tract mechanically and chemically breaks down food, so intestinal cells can absorb nutrients for the body.
