The most appropriate answer would be a stem cell.
Stem cells are the undifferentiated cells which have the capability to divide to give rise to more number of the same type of cell.

For example, the embryonic stem is undifferentiated pluripotent cells which are capable of giving rise to almost all types of cells of the body.
Answer:
These are the following answers to the items:
Pinocytosis -cell engulfs molecules in cell "drinking"
Facilitated diffusion- molecules helped by protein; move insoluble molecules
across plasma membrane
Passive diffusion- molecules move in and out freely from high to low concentration
Phagocytosis- cell engulfs microorganisms in cell "eating"
Active transport- molecules "pumped" in or out from low to high concentration
Passive diffusion- oxygen, carbon dioxide
Active transport- transports sodium, potassium
Pinocytosis- transports glucose, amino acids
