Mode of Nutrition in Amoeba: From Ingestion to Egestion
In amoeba, the mode of nutrition involves several steps from ingestion to egestion. Let's break down each process in detail:

Ingestion:
- Amoeba ingests food particles by extending its pseudopodia around the food.
- The pseudopodia surround the food particle and form a food vacuole.

Digestion:
- The food vacuole containing the ingested food fuses with lysosomes.
- Lysosomes release enzymes into the food vacuole to digest the food particles.

Absorption:
- The digested food is absorbed by the cytoplasm of the amoeba.
- The nutrients are then utilized for energy and growth.

Assimilation:
- The absorbed nutrients are used to build new cell components and repair existing ones.
- This process helps in the growth and maintenance of the amoeba.

Egestion:
- Undigested food particles or waste materials are expelled from the cell through exocytosis.
- The food vacuole containing the indigestible material fuses with the cell membrane and releases the waste outside the cell.
In conclusion, amoeba obtains nutrition through the process of ingestion, digestion, absorption, assimilation, and egestion. Each step is crucial for the survival and growth of the organism.
