What is the function of the rough endoplasmic reticulum (rough ER)? (1)
The rough endoplasmic reticulum produces protein ingredients for transport out of the cell.
What are the functions of the cell membrane? (3)
The cell membrane is a barrier that protects the cell, it absorbs nutrients and evacuates waste.
What is the function of mitochondria? (1)
