Pseudopodia form when the actin polymerization is activated. The actin filaments that form in the cytoplasm push the cell membrane resulting in the formation of temporary projection. Pseudopodia may be classified into lobopodia, filopodia, reticulopodia, axopodia, and lamellipodia. The most common is lobopodia.

How is pseudopodia formed in amoeba?

Pseudopodia are formed by some cells of higher animals (e.g., white blood corpuscles) and by amoebas. During amoeboid feeding, pseudopodia either flow around and engulf prey or trap it in a fine, sticky mesh. Protozoans have four types of pseudopodia.

What can produce pseudopods?

Amoebae are usually capable of producing pseudopodia, which are used as locomotor and food-acquiring organelles.
