VOCABULARY KEY POINTS ~
Think about: What is it? What is it used for? If it is a structure, where is it located? How does it
fit in to photosynthesis OR cellular respiration OR BOTH?
**THESE VOCABULARY have already been filled out in a worksheet distributed at the start of
the unit! ** You don’t have to re-write them here if you have that sheet…
