Process of Nutrition in Amoeba

Amoeba shows the holozoic mode of nutrition. It includes;

Ingestion

The pseudopodia extends and engulfs the food particle by the process of phagocytosis and then joins to form the food vacuole where the food is kept.

Digestion

Inside the food vacuole, the digestive enzymes from the cell cytoplasm are poured. These enzymes break down the food particles and extract the simple nutritional elements from them.

Absorption

Once the simple nutritional elements are extracted they get diffused and absorbed into the cell cytoplasm from the food vacuole providing the organism with all the nutrition required.

Assimilation

The absorbed nutrients then get distributed to all the parts and organelles of the cell where they are used to perform various cellular activities.

Egestion

The undigested particles present inside the food vacuole are then transported to the cell’s surface where the vacuole opens and throws them out of the cell into the surroundings.

Nutrition in Amoeba helps us to understand the food habits of Amoeba. Nutrition in Amoeba shows how single-celled organisms Amoeba take up their food, digest it, and throw out the waste. Nutrition in Amoeba is achieved with the help of five main steps. Amoeba being a microscopic organism shows a straightforward yet interesting process of getting nutrition. Nutrition is required for Amoeba’s survival, similar to any other living organism found on Earth. In Amoeba the holozoic mode of nutrition is easily and clearly can be observed. In this article, we will look into the definition of holozoic nutrition, Amoeba, and the process by which they get their nutrition.
