nutrition of amoeba with diagram of amoeba
Answers
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.
HEY MATE!!!
■ Amoeba takes in food using temporary finger like extension of the cell surface which fuse over the food particle forming a food vacuole.
■ Inside the food vacuole,complex substances are broken down into simpler ones which then diffuse into the cytoplasm.
■ The remaining undigested material is moved to the surface of the cell and thrown out.
