Mitochondria Chloroplasts Complete the following Venn Diagram to compare and contrast mitochondria and chloroplasts. And YES, it MUST be a Venn Diagram!!! Cellular Energy Bellringer #5

10/1—Binder Time Clear your desk of everything EXCEPT your Science Binder. As your assignments are being handed back to you, place them in the correct section of your binder. HOLE-PUNCH them & put them in the rings, NOT THE POCKETS! Order: Chronological per section. ▫Example: BR section, first paper should be the August bellringers, last should be the October bellringers.
