The question you're asking is a bit like asking "What cell does a dog come from?" Dogs are multicellular organisms, meaning they are made up of many cells, but they don't come from a single specific cell type.
However, you could ask:
* What is the origin of amoeba? Amoeba, like all life on Earth, evolved over billions of years from simpler forms of life.
* What type of cell is an amoeba? An amoeba is a type of eukaryotic cell, meaning it has a nucleus and other membrane-bound organelles.
