Question

Explain the steps involved in the nutrition of Amoeba ​

Answer 1

Answer:

Process Of Nutrition In Amoeba

The different processes involved in holozoic nutrition in amoeba are:

Ingestion

Ingestion is the process of taking in the food into the body either by swallowing or absorbing it. Amoeba pushes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis.

Digestion

Digestion is the process of breaking the insoluble and large food molecules into soluble and minute molecules. In amoeba, the food vacuoles are transported deeper into the cell and with the help of the digestive enzymes, the large insoluble particles are broken down to the simpler molecules.

Absorption

In this process of absorption, the nutrients from the digested food material are absorbed into the cell’s cytoplasm by leaving behind the undigested particles. This process is called diffusion. The excess food is stored in the form of glycogen and lipids.

Assimilation

Assimilation is the process of obtaining energy from the absorbed food molecules. In amoeba, absorbed food molecules are utilized for producing the energy required to carry out different life processes within the cell.

Egestion

Egestion is the process of excretion of undigested food material. In amoeba, this process is carried out by rupturing the cell membrane to remove the undigested food material from its body.

Answer 2

Answer:

The various steps involved in the nutrition of Amoeba are as follows :

❤️ INGESTION : Amoeba ingests the food with the help of its finger-like extensions, called pseudopodia. When a food particle approaches Amoeba, it forms pseudopodia around it and forms a food vacuole inside the Amoeba.

❤️ DIGESTION : Various enzymes from the cytoplasm enter into the food vacuole and break them down into simple soluble molecules.

❤️ ABSORPTION : The simple Soluble food is absorbed by cytoplasm of Amoeba from the food vacuole through the process of diffusion.

❤️ ASSIMILATION : Amoeba cell obtains energy from the absorbed food through respiration. This energy is utilised by Amoeba for its growth and repair of the body.

❤️ EGESTION : When a considerable amount of undigested food gets collected inside Amoeba, its cell membrane ruptures and throws out the undigested food.
