Question

What are the differences between intercellular digestion and extra cellular digestion?

Answer 1

In intracellular digestion, the breakdown of food materials into small molecules occurs inside the food vacuoles within the cell. In extracellular digestion, the breakdown of food materials into small molecules occurs outside the cell in the lumen of the alimentary canal or on the decaying organic materials.

Answer 2

Answer:

Intracellular digestion Extracellular digestion

In intracellular digestion, the breakdown of food materials into small molecules occurs inside the food vacuoles within the cell. In extracellular digestion, the breakdown of food materials into small molecules occurs outside the cell in the lumen of the alimentary canal or on the decaying organic materials.

In this type of digestion, the ingestion occurs through the phagocytic vesicles. In this type of digestion, ingestion occurs through the mouth.

Digestive enzymes involve lysozyme that secretes into the food vacuole. In this digestion, digestive enzymes secreted from the glands of the alimentary canal.

In intracellular digestion, only chemical digestion takes place. In extracellular digestion, both chemical and mechanical digestion occurs.

Nutrients formed by this type of digestion diffuses into the cytoplasm through the membrane of the vacuole. Nutrients formed by this type of digestion are absorbed into the blood through the gut epithelia.

The materials that are not digestible get excreted through the exocytosis. The materials that are not digestible get excreted through the anus.

It is a simple mechanism of digestion that involves vesicles. It is a complex mechanism of digestion that involves the organs and glands.

It mainly occurs in protozoans. It follows in bacteria, fungi, and animals with the alimentary canal
