Photosynthesis and Cellular Respiration Diagram Labeling (6-8 ... - Free Printable

Let's solve the Photosynthesis and Cellular Respiration Diagram step by step. This diagram shows the interconnected processes of photosynthesis (in plants) and cellular respiration (in both plants and animals), highlighting how energy and matter cycle through ecosystems.

🔍 Step-by-Step Explanation:

#### 🌿 Photosynthesis (Occurs in plant cells, mainly in chloroplasts)
This process converts light energy into chemical energy using carbon dioxide and water to produce glucose and oxygen.

Equation:
> Carbon Dioxide + Water + Light Energy → Glucose + Oxygen

#### 🔥 Cellular Respiration (Occurs in all living cells, in mitochondria)
This process breaks down glucose to release energy (ATP) for cellular work, producing carbon dioxide and water as byproducts.

Equation:
> Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)

✔ Answers:

1. Carbon Dioxide (CO₂)
- Plants take in CO₂ from the air during photosynthesis.
- Arrow points from atmosphere to plant leaf → CO₂

2. Water (H₂O)
- Water is absorbed by roots and transported to leaves.
- Used in photosynthesis → H₂O

3. Glucose (C₆H₁₂O₆)
- The product of photosynthesis; an energy-rich molecule.
- Arrows show it being used by animals and plants → Glucose

4. Mitochondria
- Organelle in animal cells where cellular respiration occurs.
- Arrow points to the structure inside the animal cell → Mitochondria

5. Oxygen (O₂)
- Produced as a byproduct of photosynthesis.
- Released into the atmosphere and used in cellular respiration → Oxygen

6. Glucose
- Labeled as "energy rich" — this is the fuel for cellular respiration.
- Goes into the mitochondria → Glucose

7. Carbon Dioxide (CO₂)
- A waste product of cellular respiration.
- Released back into the atmosphere → CO₂

🔁 Summary of the Cycle:

- Plants use sunlight, CO₂, and H₂O to make glucose and O₂ (photosynthesis).
- Animals consume glucose (from plants or other animals) and use O₂ to break it down in mitochondria (cellular respiration), releasing energy, CO₂, and water.
- CO₂ is released and reused by plants — forming a continuous cycle.

✔ Final Answer Key:

1. Carbon Dioxide (CO₂)
2. Water (H₂O)
3. Glucose
4. Mitochondria
5. Oxygen (O₂)
6. Glucose
7. Carbon Dioxide (CO₂)
