in the endoplasmic reticulum
What does the golgi apparatus (golgi complex) do? - ANS ✓synthesizes materials such as
proteins that are transported out of the cell
Where is the golgi apparatus (golgi complex) located? - ANS ✓near the nucleus
What does the golgi apparatus (golgi complex) consist of? - ANS ✓layers of membranes
What are vacuoles? - ANS ✓sacs used for storage, digestion, and waste removal
How are vacuoles presented in different cells (plant/animal)? - ANS ✓plant: one large

found within the plasma membrane, but not within the nucleus
What does the cell membrane (plasma membrane) do? - ANS ✓defines the cell by acting as
a barrier, helps keep cytoplasm in and substances located outside the cell, and determines
