What is a cytoskeleton?
The membrane-bound organelle that packages and distributes materials such as proteins
What is the Golgi complex?
They are small because of their limit in their outer surface area

What is an organelle?
The process of breaking down food to release its energy.
What is cellular respiration?
The organelle the is only in plants, where photosynthesis occurs
