explain nutrition in amoeba​

Answer 1

$\Large{ \cdot{ \underline{ \red{ \rm{Nutrition \: in \: Amoeba...}}}}}$

Amoeba is a unicellular organism generally found in water. It is protozoa, hence it is a eukaryote. The mode of nutrition found in Amoeba is holozoic type of nutrition. The process of obtaining food is by $\large{\rm{\purple{Phagocytosis}}}$ i.e. cell eating. The nutrition in amoeba takes in several steps.

The various steps involved in the digestion of amoeba are:

• $\large{\rm{\purple{Ingestion}}}$ : Since it is a unicellular organism, only a single cell is responsible for carrying out all the vital activities. Food is ingested with the help of False feet $\large{\rm{\red{Pseudopodia}}}$. It engulf its prey nearby as its food. They form pseudopodia around it and forms a food vacuole which is the temporary stomach in Amoeba.
• $\large{\rm{\purple{Digestion}}}$: The enzymes from surrounding cytoplasm and lysosome enters into the food vacuole and break down the food for digesting it.
• $\large{\rm{\purple{Absorption}}}$: The digested food is now absorbed by cytoplasm by simple diffusion and the food vacuole disappears.
• $\large{\rm{\purple{Assimilation}}}$: The digested food absorbed by amoeba is used to obtain energy for respiration and to obtain various nutrients. They also grow in size.
• $\large{\rm{\purple{Egestion}}}$: The undigested food is then expelled out of the body of the Amoeba. They are thrown out directly from its body.

Answer 2

Hlw MATE, HERE IS YOUR ANSWER.....

⬛ Amoeba takes in food using temporary finger like extensions of the cell surface which fuse over the food particles forming the food vacuole.

⬛ Inside the food vacuole, complex substances are broken into simpler substances which then diffuses into cytoplasm.

⬛ The remaining undigested material is moved to the surface of the cell and then thrown out of the cell.
