Final answer:
The original cell, known as the progenote, is the common genetic ancestor of all living organisms. Cells are the basic units of life and they come from preexisting cells through cell division.
Step-by-step explanation:
The original cell, also known as the first cell, is the progenote, which is the progenitor of all living organisms. It is considered our common genetic ancestor. Cells are the basic units of life and all cells come from preexisting cells through cell division. They have a gel-like cytoplasm enclosed by a plasma membrane and contain DNA as the genetic material.
