Pseudopods or pseudopodia (false feet) are temporary projections of eukaryotic cells. Cells having this faculty are generally referred to as amoeboids.
Formation
First, the cell surface extends a membrane process, named lamellipodium. Polymerization of actin takes place and form filaments at the leading edge, which subsequently will blend into one another to form networks. We suppose that actin polymerization is at the origin of the force propelling the cell forwards.
Function
They are involved in a variety of cell activities, most notably:
Mechanical role
Pseudopods are one of the three locomotion modes of unicellular organisms (together with flagella and cilia).
Sensory role
Pseudopods also capture prey phagocytosis. Phagocytosis pseudopods have arisen in a number of different protist groups, but also in some cells (phagocytes) in multicellular organisms.

A false foot like an amoeba extends itself with to move, and containing chloroplasts. That'd be my guess.
