Biology worksheet designed to help students master the key differences between photosynthesis and cellular respiration through vocabulary matching and equation analysis.

Problem Analysis:

The worksheet focuses on photosynthesis and cellular respiration, two fundamental processes in biology. The task involves matching phrases with the correct terms and filling out a table comparing cellular respiration and photosynthesis.

#### Part 1: Vocabulary Matching
We need to match the phrases on the left with the most appropriate term from the list on the right. Let's analyze each phrase:

1. Organisms that make their own food
- These are organisms that produce their own food through photosynthesis.
- Answer: J. Autotrophs

2. Site of photosynthesis
- Photosynthesis occurs in chloroplasts, which are organelles found in plant cells.
- Answer: A. Chloroplasts

3. Process occurs in cytoplasm
- Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm.
- Answer: G. Glycolysis

4. C₆H₁₂O₆
- This is the chemical formula for glucose, a simple sugar.
- Answer: D. Glucose

5. Process does not require oxygen
- Anaerobic processes do not require oxygen. An example is anaerobic respiration or fermentation.
- Answer: B. Anaerobic

6. Process requires oxygen
- Aerobic processes require oxygen. Cellular respiration is an aerobic process.
- Answer: C. Aerobic

7. Adenosine triphosphate
- ATP (adenosine triphosphate) is the energy currency of the cell.
- Answer: E. ATP

8. Energy storing molecule
- ATP is the primary energy-storing molecule in cells.
- Answer: E. ATP

9. The anaerobic process of splitting glucose and forming two molecules of pyruvic acid
- Glycolysis is the anaerobic process where glucose is split into two molecules of pyruvic acid.
- Answer: G. Glycolysis

10. The ability to do work
- Energy is defined as the ability to do work.
- Answer: H. Energy

#### Matched Answers:
1. J. Autotrophs
2. A. Chloroplasts
3. G. Glycolysis
4. D. Glucose
5. B. Anaerobic
6. C. Aerobic
7. E. ATP
8. E. ATP

#### Part 2: Fill Out the Table
The table compares cellular respiration and photosynthesis in terms of reactants, products, and the organelle involved. Let’s fill it out step by step.

##### Cellular Respiration:
- Reactants: Oxygen (O₂), glucose (C₆H₁₂O₆)
- Products: Carbon dioxide (CO₂), water (H₂O), and ATP (energy)
- Organelle: Mitochondria

##### Photosynthesis:
- Reactants: Carbon dioxide (CO₂), water (H₂O), and light energy
- Products: Glucose (C₆H₁₂O₆) and oxygen (O₂)
- Organelle: Chloroplasts

#### Filled Table:
| | Cellular Respiration | Photosynthesis |
|---------------|------------------------------------------|--------------------------------------|
| Reactants | Oxygen (O₂), glucose (C₆H₁₂O₆) | Carbon dioxide (CO₂), water (H₂O), light energy |
| Products | Carbon dioxide (CO₂), water (H₂O), ATP | Glucose (C₆H₁₂O₆), oxygen (O₂) |
| What organelle? | Mitochondria | Chloroplasts |
