In this process, the pseudopodia surround and engulf a bacterium or other food source. A food vacuole forms around the food particle as it is internalized by the amoeba. Organelles known as lysosomes fuse with the vacuole releasing digestive enzymes inside the vacuole.

Ya...it's lysosome...since the food vacuole contains the engulfed food materials, it has to be digested. So, the lysosome which has many hydrolytic enzymes, is present around the food vacuole in abundance....

Introduction:
Amoeba is a unicellular organism that belongs to the group of protozoans. It is capable of engulfing and digesting its food through a process called phagocytosis. During phagocytosis, a food vacuole is formed within the cytoplasm of Amoeba, which contains the engulfed food particle. Various cell organelles play important roles in the process of phagocytosis and digestion of food in Amoeba.

Lysosomes:
Lysosomes are membrane-bound organelles that contain digestive enzymes. They are involved in the intracellular digestion of food particles. Lysosomes fuse with the food vacuole, releasing their enzymes into it. These enzymes break down complex molecules into simpler ones, which can be absorbed and utilized by the cell. Lysosomes are abundant around the food vacuole in Amoeba due to their crucial role in the digestion of engulfed food particles.

Function of Lysosomes:
1. Digestion: Lysosomes contain hydrolytic enzymes that break down proteins, nucleic acids, carbohydrates, and lipids into smaller molecules.
2. Waste disposal: Lysosomes also help in the elimination of waste materials generated during cellular metabolism.
3. Autophagy: Lysosomes are involved in the degradation of worn-out organelles and cellular components through a process called autophagy.
4. Defense mechanism: Lysosomes also play a role in the defense mechanism of the cell by destroying foreign particles, bacteria, and viruses.

Other organelles:
While lysosomes are the most abundant organelles around the food vacuole in Amoeba, other organelles also contribute to the process of phagocytosis and digestion of food:
- Golgi body: The Golgi body is involved in modifying, sorting, and packaging the enzymes produced by the cell. It plays a role in the formation of lysosomes and their fusion with the food vacuole during phagocytosis.
- Ribosomes: Ribosomes are responsible for protein synthesis. They are involved in producing the enzymes that are later packaged into lysosomes.
- Mitochondria: Mitochondria are the powerhouses of the cell, responsible for generating energy in the form of ATP. They provide the necessary energy for the phagocytosis process and the functioning of lysosomes.

Conclusion:
In conclusion, the most abundant organelle around the food vacuole in Amoeba is the lysosome. Lysosomes contain digestive enzymes that break down the engulfed food particles. They play a crucial role in the intracellular digestion of food in Amoeba. While other organelles such as the Golgi body, ribosomes, and mitochondria also contribute to the process, lysosomes are specifically abundant around the food vacuole due to their essential role in digestion.
