Cellular Respiration - Worksheet | Distance Learning | Teaching ... - Free Printable

Looking at this zoomed-in view of the output from cellular respiration, I can see:

- An arrow pointing from the mitochondrion (labeled "Cellular Respiration") to a blank box
- This represents the products of cellular respiration that go back to support photosynthesis
- I know that cellular respiration produces carbon dioxide and water as byproducts
- These products are then used as inputs for photosynthesis, completing the cycle

Now I have enough information to label all the boxes in the diagram. Let me summarize what should go in each box:

1. Below the sun (input for photosynthesis): Water (H₂O) - since sunlight is already shown, and photosynthesis needs water and CO₂
2. The two boxes between photosynthesis and cellular respiration: Glucose and Oxygen (products of photosynthesis, inputs for cellular respiration)
3. The box below cellular respiration: Carbon Dioxide and Water (products of cellular respiration, inputs for photosynthesis)

For Question 3: "In what organelle does cellular respiration take place?"
The diagram clearly shows cellular respiration occurring in the mitochondrion. The mitochondrion is often called the "powerhouse of the cell" because it's where cellular respiration takes place to produce energy (ATP).

Therefore, the answer to Question 3 is c) Mitochondria.

Let me now provide the complete labeled diagram solution.

The completed diagram should be labeled as follows:

- Below the sun: Water (H₂O) [or could also be Carbon Dioxide - both are inputs for photosynthesis along with sunlight]
- The two boxes after photosynthesis (inputs for cellular respiration): Glucose + Oxygen
- The box after cellular respiration (inputs for photosynthesis): Carbon Dioxide + Water

For Question 3: In what organelle does cellular respiration take place?
Answer: c) Mitochondria

This makes sense because:
- Photosynthesis occurs in chloroplasts and converts sunlight, water, and carbon dioxide into glucose and oxygen.
- Cellular respiration occurs in mitochondria and uses glucose and oxygen to produce energy (ATP), releasing carbon dioxide and water as byproducts.
- The cycle is continuous: the outputs of one process become the inputs of the other.
