Explain the process of nutrition in Amoeba.
Answers
Answer:
Nutrition in an Amoeba occurs through a process called phagocytosis where the entire organism pretty much engulfs the food it plans on eating up. The mode of nutrition in amoeba is known as holozoic nutrition. It involves the ingestion, digestion and egestion of food material.
Answer:
Amoeba shows holozoic nutrition which is comprised of following steps:
Ingestion, Digestion, Absorption, Assimilation and Egestion
Ingestion: Amoeba makes finger-like projections outside its body. These projections are called pseudopodia. Amoeba traps food particle with pseudopodia. After that, amoeba takes in the food particle; along with water.
Digestion: Amoeba makes food vacuole after ingesting the food particle. Enzymes are released in the food vacuole for digestion.
Absorption: After digestion, nutrients enter the cytoplasm through osmosis.
Assimilation: Nutrients are utilized by the cell for various purposes.
Egestion: Food vacuole goes near the cell membrane to empty its contents outside the cell. This results in expulsion of waste materials from the cell.
