Explain the process of nutrition in amoeba.draw labelled diagram to show the various steps in the nutrition of amoeba
Answers
The above picture might be helpful. Though I haven't drawn it myself, I think it's the correct diagram.
Amoeba is a unicellular organism that follows holozoic mode of nutrition. The process of obtaining food by Amoeba is called phagocytosis.
1. Injestion: Amoeba ingests food particle by forming temporary finger like projections called pseudopodia around it. The food is engulfed forming a food vacuole.
2. In the food vacuole, complex substances are broken down into simpler substances by digestive enzymes.
3. Absorption: The digested food present in the food vacuole diffuse into the cytoplasm. After this the food vacuole disappears.
4. Assimilation: Food absorbed is used by Amoeba for various processes.
5. Egestion: The remaining undigested material moves to the surface of the cell.
The cell membrane ruptures at any place and the undigested food is thrown out of the body.
Answer:
The mode of nutrition in Amoeba is called Holozoic nutrition.
The nutrition in amoeba takes place in the following steps:
1. Ingestion: The process of ingestion is nothing but intake of food into the body. Amoeba is unicellular and hence it does not have mouth, Amoeba takes the food into the body by forming structures called pseudopodia around the food particle. This pseudopodia forms a vacuole around the food particle called food vacuole and the vacuole is taken inside the cell.
2. Digestion: The food particle inside the vacuole is broken down into soluble particles by digestive enzymes inside the vacuoles.
3. Absorption: The broken food particles is absorbed into the cytoplasm of amoeba by diffusion. The food particles which are unabsorbed are left inside the vacuole.
4. Assimilation: The absorbed food is converted into energy in this step.
5. Egestion: The undigested food in the food vacuole is thrown out from the cell.
