Feeding And Digestion In Amoeba

Amoeba possesses a holozoic mode of nutrition and process is known as  “phagocytosis”. The basic processes involved in the nutrition  include:

Amoeba possesses a holozoic mode of nutrition and process is known as  “phagocytosis”. The basic processes involved in the nutrition  include:

(Phagocytosis in Amoeba)

Ingestion: Amoeba takes in its food through this process. Initially, it pushes out its pseudopodia so that it can encircle the food. After this, it engulfs the food, thus forming a bag-like structure called food vacuole. The process is known as “phagocytosis”.

Digestion: This step follows ingestion. The food vacuoles are rich in various digestive enzymes. These enzymes break down large insoluble foodstuffs consequently yielding simple soluble molecules.

Absorption: It is the process of absorption of the digested food material into the cytoplasm leaving behind the undigested food material. Sometimes the amoeba absorbs large quantities of food. What happens to the excess food? Well, the excess food gets stored in the form of glycogen as well as lipids.

Assimilation: This is the “utilization” process. During this process, the absorbed food is utilized for energy production, growth, repair as well as for multiplication.

Egestion: Finally, the cell membrane gets ruptured so that the undigested food material is thrown out of the body.

INGESTION  ⇒  DIGESTION ⇒  ABSORPTION  ⇒  ASSIMILATION  ⇒  EGESTION

Answer 2

The method involved in acquiring food from Amoeba is called phagocytosis.

Characteristics of Amoeba:

• one-celled amoeba is a unicellular life form.
• It goes through intracellular processing.
• It is holozoic.

Process of feeding and digestion:

• Ingestion: When a food molecule is close to the Amoeba, it structures brief finger-like projections called pseudopodia around the food molecule and immerses it.
• Processing: The food is processed in the food vacuole with the assistance of compounds.
• Assimilation: It is then caught up in the cytoplasm of the Amoeba by dispersion.
• Osmosis: The retained food gives energy and a piece of nourishment is utilized for development.
• Egestion: Food scraps that haven't been digested and are thrown out.

Role of pseudopodia:

• one-celled amoeba is an infinitesimal organic entity which has fingerlike known as pseudopodia.
• The single adaptable cell broadens its pseudopodia around the food and overwhelms it.
• The food is caught in the food vacuole where it is processed by the stomach-related chemical.
• Lastly the food is retained and appropriated all through the body.
