The cell divides and grows in the organ of origin, causing a localized tumor. Cancer cells then spread to adjacent tissues or regional lymph node drainage areas, and then advance to distant organs or structures, creating metastatic tumors.

Answer:
In an open system matter and energy can be transferred ·
In a closed system only energy can be exchanged ·

As an open system the cell allows nutrients to enter the cell and waste products to exit the cell ·
The cell does this through the use of a semi-permeable membrane
