Introduction:
Amoeba is a unicellular organism that uses pseudopodia to move and capture food. It has a unique structure called the food vacuole, which is responsible for digestion and absorption of nutrients. In this article, we will discuss why the food vacuole of amoeba is called a temporary stomach.

Temporary Stomach:
The food vacuole of amoeba is called a temporary stomach because it performs the same function as the stomach in higher organisms. It is responsible for the digestion of food particles that are captured by the pseudopodia. The food vacuole is formed when the pseudopodia engulf food particles and fuse together.

Process of Digestion:
The food vacuole contains digestive enzymes that break down the food particles into smaller molecules. These molecules are then absorbed by the cell membrane and used for energy or growth. Once the digestion is complete, the food vacuole releases the undigested material out of the cell.

Role in Nutrition:
The food vacuole is an essential part of the amoeba's nutrition. It allows the organism to feed on a wide variety of food sources, including bacteria, algae, and small protozoans. The process of digestion in the food vacuole ensures that the amoeba can extract the maximum amount of nutrients from its food.

Conclusion:
In conclusion, the food vacuole of amoeba is called a temporary stomach because it performs the same function as the stomach in higher organisms. It is responsible for the digestion and absorption of nutrients, making it an essential part of the amoeba's nutrition. Understanding the role of the food vacuole is crucial to understanding the biology of unicellular organisms.

Amoeba ingests food by forming temporary finger-like projectionscalled pseudopodia around it. The food is engulfed with a little surrounding water to form a food vacuole ('temporary stomach') inside the Amoeba.
