Question

The digestion of food in amoeba is
A. Intracellular
B. Intercellular
C. Intravenous
D. None of these

Answer 1

We have to remember that one can name a microscopic organism which comprises fingerlike known pseudopodia as an amoeba. The pseudopodia are made to extend around the food and help the amoeba to engulfs the food materials. It is already known that there exist five steps in the digestion of food in amoeba. We can say that the Ingestion, Digestion, Absorption, Assimilation, and Egestion as the steps included in the process of the digestion of food in the animals like amoeba

Complete answer: Now we can discuss about the process of food by amoeba as,
We can say that the digestion in amoeba is intracellular as it is taking place within the cell.
The food vacuole which is also called as gastric vacuole is formed by the cell membrane into which the remaining food is taken. In addition to the food vacuole or gastric vacuole, a small part of the cytoplasm is also formed by the cell membrane.
The process of intracellular digestion includes the digestion which takes place outside the cell in the cavity of the alimentary canal. In such a type of digestion process, it is known that the digested food is absorbed into the cells.
The process of digestion in which the digestive tract has no ability to absorb the nutrients adequately is called Intravenous feeding. It generally occurs in severe malabsorption disorders.
So, the correct answer is “Option A”.

Note:
We must remember that the cytoplasmic movements make the vacuoles which are formed by the cell membranes to transport deeper into the cells. We can say that this is the only place where they were allowed to fuse with lysosomes that contain enzymes. Thus, we can say that intracellular digestion takes place in the organisms like amoeba.
