it's either pinched off of rough ER, smooth ER, the Golgi App., or the cell membrane.

In the example of the amoeba or a white blood cell for that matter the agent to be consumed or removed is engulfed by the cell. Literally the cell wraps itself around the particle being engulfed. Ultimately the cell membrane must fuse around the particle and form a vesicle which becomes intracellular. Thereafter, such vesicles often fuse with lysosomes which will release enzymes into the vesicle to further degrade the particle.

When the object entering te cell is moving in to it, it goes through the phospho-lipid bilayer, as it is entering a peice of the membrane pinches off surrounding the object entering the cell forming a vesicle (The membrane folds around the object sealing it off in a grease bubble so to speak).
