Amoeba acquires its food through the process of ______.

endocytosis

The correct answer is Option (3)- endocytosis

Amoeba acquires its food through the process of endocytosis.

Explanation:

• Amoeba is a unicellular organism that belongs to the group of protozoans. It lacks specialized structures like a mouth or digestive system.
• Endocytosis is the process by which Amoeba captures and engulfs its food. It involves the formation of pseudopodia (temporary extensions of the cell membrane) around the food particle.
• The pseudopodia merge and enclose the food particle within a vesicle known as a food vacuole.
• Once the food particle is trapped in the food vacuole, the vesicle fuses with lysosomes, which contain enzymes. These enzymes break down the food into simpler substances that can be absorbed and utilized by the Amoeba for energy and nutrition.
• The undigested remains are expelled from the cell through a process called exocytosis.

In summary, Amoeba relies on endocytosis for the ingestion of food particles, demonstrating a unique feeding mechanism in unicellular organisms.
