Read each question carefully and provide your best answer. Some questions may require you to refer to diagrams or your knowledge of cell biology.
1. Which organelle is primarily responsible for photosynthesis in plant cells?
Mitochondrion
Chloroplast
Nucleus
Ribosome
2. The process of cellular respiration occurs in which two main stages (and associated locations) within eukaryotic cells?
Glycolysis (cytoplasm) and Krebs cycle (nucleus)
Light-dependent reactions (thylakoid) and Calvin cycle (stroma)
Glycolysis (cytoplasm) and oxidative phosphorylation (mitochondria)
Fermentation (mitochondria) and electron transport chain (cytoplasm)
3. The primary energy currency of the cell is .
4. Photosynthesis converts light energy into energy stored in glucose.
5. In the absence of oxygen, cells can undergo to produce a small amount of ATP.
Match the term on the left with its correct description on the right.
6. Chlorophyll
a. Site of cellular respiration
7. Mitochondrion
