Explain nutrition in Amoeba.
Answers
Answer:
Mode of Nutrition in Amoeba
Amoeba takes its nutrition through a process called phagocytosis where the entire organism swallows the food it plans on eating up. The mode through which an amoeba engulfs nutrition is known as holozoic nutrition. It leads to the process of ingestion, digestion and egestion of food material. Amoeba doesn’t not have any specialized organs for nutrition. Its entire process is carried through the body surface with the assistance of pseudopodia.
Process of Nutrition in Amoeba
The process by which organisms engulfs nutrition inside the body either solid or liquid food is called the Holozoic Nutrition. The intake of nutrition takes place in the in the following 5 steps:
Ingestion
Digestion
Absorption
Assimilation
Egestion
Explained Process Of Nutrition In Amoeba
The processes involved in holozoic nutrition in amoeba are:
Ingestion
The process of taking in the food into the body either by swallowing or absorbing it is called the procedure of Ingestion. Amoeba oozes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis.
Digestion
The process of breaking the insoluble and enormous food molecules into soluble and minute molecules is called the process of Digestion. In amoeba, the food vacuoles are put deeper into the cell, and with the assistance of the digestive enzymes, the massive insoluble particles are churned down to the simpler molecules.
Absorption
In this process of absorption, the nutrients from the digested food material are absorbed by the cell’s cytoplasm by keeping behind the undigested particles. This process is called diffusion. The excess food is stored as a form of glycogen and lipids.
Assimilation
The process of obtaining energy from the absorbed food molecules is called the procedure of Assimilation. In amoeba, absorbed food molecules are utilized for producing the energy required to hold different life processes within the cell.
Egestion
The process of excretion of undigested food material is called Egestion. In amoeba, this process is administered by rupturing the cell wall to take out the undigested food material from its body.
