Review Questions (answer on separate paper) What is the function of the endoplasmic reticulum? What is the function of the Golgi Apparatus? What is the function of the lysosome? How are vacuoles and plastids similar? When a plant is not watered for a long time, what cell organelle is the first to be affected?

Name the three types of plastids and what is stored in each. Fill in the blanks: _________ are the basic structural and functional unit of living things.

The endoplasmic reticulum is like _____________ since they both are paths to get from one place to another. The Golgi Apparatus is like _____________ since they are both places where things are packaged and shipped. Lysosomes are like _____________ since they both break down materials or recycle old materials. Vacuoles are like _________ since they both store water for later use.

Plastids are like ___________ since they both store chemicals.
