This diagram illustrates the relationship between
photosynthesis and
cellular respiration, two essential biological processes that are interconnected in the flow of energy and matter in living organisms.
Let’s go step by step to fill in the blanks and explain the solution.
---
🔹 Step 1: Identify the Organelles
- The
green oval with stacked disks (thylakoids) is a
chloroplast → site of
photosynthesis.
- The
blue bean-shaped structure with folds (cristae) is a
mitochondrion → site of
cellular respiration.

🔹 Step 2: Understand the Processes
#### 🌿
Photosynthesis (in chloroplasts)
This process converts
light energy into
chemical energy (glucose).
The general equation is:
>
Carbon dioxide + Water + Light energy → Glucose + Oxygen
So:
- Inputs: CO₂, H₂O, light
- Output: Glucose, O₂
#### 🔬
Cellular Respiration (in mitochondria)
This process breaks down glucose to release energy (ATP).
The general equation is:
>
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
So:
- Inputs: Glucose, O₂
- Outputs: CO₂, H₂O, chemical energy (ATP)

🔹 Now Fill in the Diagram
Let’s label each blank based on the flow:
#### Top Part – Photosynthesis
-
Star at top: "Light energy" → goes into chloroplast.
-
Chloroplast labeled:
Photosynthesis
-
Inputs:
- One box:
Carbon dioxide
- Other box:
Water
-
Outputs:
- One box:
Glucose
- Other box:
Oxygen
#### Bottom Part – Cellular Respiration
-
Mitochondria labeled:
Cellular respiration
-
Inputs:
- One box:
Glucose
- Other box:
Oxygen
-
Outputs:
- One box:
Carbon dioxide
- Other box:
Water
-
Star at bottom: "Chemical energy" → released from cellular respiration.

-
Chloroplast: Photosynthesis
-
Inputs (left side):
- Box 1: Carbon dioxide
- Box 2: Water
-
Outputs (right side):
- Box 1: Glucose
- Box 2: Oxygen
#### Bottom Section (Cellular Respiration):
-
Mitochondria: Cellular respiration
-
Inputs (left side):
- Box 1: Glucose
- Box 2: Oxygen
-
Outputs (right side):
- Box 1: Carbon dioxide
- Box 2: Water
-
Bottom star: Chemical energy

🔁 Key Concept: Interconnection
- The
products of photosynthesis (glucose and oxygen) become the
reactants for cellular respiration.
- The
products of cellular respiration (CO₂ and water) are used again in
photosynthesis.
- This creates a
cycle of energy and matter between plants and animals.

📝 Summary:
| Process | Location | Inputs | Outputs |
|--------|---------|--------|--------|
|
Photosynthesis | Chloroplast | CO₂, H₂O, Light | Glucose, O₂ |
|
Cellular Respiration | Mitochondria | Glucose, O₂ | CO₂, H₂O, ATP (Energy) |
✔ This diagram shows the
interdependence of these two processes in ecosystems.
