Consider the following phagocytic events in Amoeba.
A. Engulfed food particle.
B. Extensions of the plasma membrane as pseudopodia around the food particle.
C. Food particle containing vacuole in the cytoplasm.
D. Approaching to the food particle.
Which of the following is the correct sequence of phagocytosis?

The correct option is C D - B - A - C
Phagocytosis:

Approaching to the food particle

Extensions of plasma membrane as pseudopodia around the food particle

Engulfed food particle

Food particle containing vacuole in the cytoplasm.

Phagocytosis is the process by which a cell—often a phagocyte or a protist—engulfs a solid particle to form an internal vesicle known as a phagosome. Phagocytosis was first noted by Canadian physician William Osler and later studied by Élie Metchnikoff. Phagocytosis is a specific form of endocytosis involving the vascular internalisation of solids such as bacteria by an organism and is therefore distinct from other forms of endocytosis such as the vesicular internalisation of various liquids (pinocytosis). Phagocytosis is involved in the acquisition of nutrients for some cells. Thus, the correct answer is option C.
