Question

Sort the steps followed by an amoeba when a food particle comes close to its surface.

• A. Exocytosis
• B. Phagocytosis
• C. Phagosome formed
• D. Digestion
• E. Pseudopodia form

Answer 1

When a food particle comes closer to an amoeba, it sends out cytoplasmic projections called pseudopodia. Pseudopodia creates a wave which brings the food particle closer to the surface. The pseudopodia then join thereby, trapping the particle within it. This results in a structure called phagosome, which is similar to a food vacuole. The contents of phagosome are digested and the wastes are sent out by a process called exocytosis.
