Amoeba Digestion Process:

Amoeba is a unicellular organism that feeds on other small organisms such as bacteria, algae, and other protozoans. The digestion process in amoeba occurs in the food vacuoles.

Formation of Food Vacuoles:

When amoeba engulfs the food particles, the food particles are enclosed in a vesicle called a food vacuole. The food vacuole is formed by the cell membrane that engulfs the food particle and forms a vesicle around it.

Process of Intracellular Digestion:

Once the food particle is enclosed in the food vacuole, the digestive enzymes are secreted into the food vacuole. The enzymes then break down the food particles into simpler molecules. The process of breaking down the food particles into simpler molecules is called intracellular digestion.

Formation of Residual Body:

After the digestion is complete, the undigested particles and waste material are left behind in the food vacuole. This undigested material is then expelled out of the cell through the process of exocytosis. The remaining undigested material is left behind in the food vacuole and is called the residual body.

Excretion:

The residual body is expelled out of the cell through the process of exocytosis. The process of exocytosis involves the fusion of the food vacuole with the cell membrane, and the undigested material is expelled out of the cell.

Conclusion:

In conclusion, amoeba digests its food in the food vacuole through the process of intracellular digestion. The undigested material is expelled out of the cell through the process of exocytosis. This process helps amoeba to obtain nutrients required for its growth and survival.
