draw a diagram of amoeba and explain the process of ingestion and nutrients in amoeba
Answers
Hello, here is your answer
Nutrition in amoeba: Nutrition in amoeba involves the following steps
Nutrition in amoeba: Nutrition in amoeba involves the following steps (i) Ingestion- Amoeba has no mouth for ingestion of food. It ingests the food by using its pseudopodia. The food is engulfed with little water to form a food vacuole.

(ii) Digestion- The food is digested by digestive enzymes present in the cytoplasm which breaks the food into small soluble molecules by chemical reactions.

(iii) Absorption- The digested food is absorbed directly into the cytoplasm by diffusion. The digested food spreads out from the food vacuole into the whole cell and after absorption the food vacuole disappears.

(iv) Assimilation- Food is used to obtain energy through respiration and the remaining part of the food is used for growth. (v) Egestion- The undigested food collects inside the cell and the cell membrane ruptures. Through this, the undigested food is thrown out of the body.
Answer:
The mode of nutrition in Amoeba is called Holozoic nutrition. The nutrition in amoeba takes place in the following steps: 1. Ingestion: The process of ingestion is nothing but intake of food into the body. Amoeba is unicellular and hence it does not have mouth, Amoeba takes the food into the body by forming structures called pseudopodia around the food particle. This pseudopodia forms a vacuole around the food particle called food vacuole and the vacuole is taken inside the cell. 2. Digestion: The food particle inside the vacuole is broken down into soluble particles by digestive enzymes inside the vacuoles. 3. Absorption: The broken food particles is absorbed into the cytoplasm of amoeba by diffusion. The food particles which are unabsorbed are left inside the vacuole. 4. Assimilation: The absorbed food is converted into energy in this step. 5. Egestion: The undigested food in the food vacuole is thrown out from the cell.
