Comparing Photosynthesis and Cellular Respiration worksheet | Live ... - Free Printable

Let's solve this step-by-step. The image is a diagram comparing photosynthesis and cellular respiration, showing the inputs, outputs, and locations of these two processes.

🔍 Step 1: Understand the Diagram

- The green oval with stacked structures (thylakoids) is a chloroplast, where photosynthesis occurs.
- The red oval with folded inner membranes (cristae) is a mitochondrion, where cellular respiration occurs.
- The orange arrows represent photosynthesis (inputs → chloroplast → outputs).
- The green arrows represent cellular respiration (inputs → mitochondria → outputs).
- The sun symbols indicate energy input/output.

#### Labeling the Diagram:

Top left sun:
→ Sunlight (energy source for photosynthesis)

Top green box (above chloroplast):
→ Chloroplasts (site of photosynthesis)

Top right green box (above mitochondria):
→ Mitochondria (site of cellular respiration)

Orange arrows (Photosynthesis inputs):
- From bottom left → chloroplast: Water
- From bottom center → chloroplast: Carbon dioxide

Green arrows (Cellular respiration inputs):
- From top right → mitochondria: Glucose
- From top center → mitochondria: Oxygen

Outputs:
- From chloroplast → bottom left: Glucose
- From chloroplast → bottom center: Oxygen
- From mitochondria → bottom right: Carbon dioxide
- From mitochondria → bottom far right: Water

Bottom right sun:
→ ATP (energy released during cellular respiration)

✔ Final Diagram Labels:

| Box | Label |
|-----|-------|
| Top left sun | Sunlight |
| Top green box (above chloroplast) | Chloroplasts |
| Top right green box (above mitochondria) | Mitochondria |
| Orange arrow (left input to chloroplast) | Water |
| Orange arrow (center input to chloroplast) | Carbon dioxide |
| Green arrow (right input to mitochondria) | Glucose |
| Green arrow (center input to mitochondria) | Oxygen |
| Output from chloroplast (bottom left) | Glucose |
| Output from chloroplast (bottom center) | Oxygen |
| Output from mitochondria (bottom right) | Carbon dioxide |
| Output from mitochondria (far right) | Water |
| Bottom right sun | ATP |

✔ Now, answer the written questions:

> The outputs/products of photosynthesis are the _________ of _____________.
→ The outputs/products of photosynthesis are the inputs of cellular respiration.
*(Because glucose and oxygen from photosynthesis are used in cellular respiration)*

> The outputs/products of cellular respiration are the _________ of _____________.
→ The outputs/products of cellular respiration are the inputs of photosynthesis.
*(Because CO₂ and water from respiration are used in photosynthesis)*

> The purpose of photosynthesis is
→ To convert light energy into chemical energy (glucose) using carbon dioxide and water, producing oxygen as a byproduct.

> The purpose of cellular respiration is
→ To break down glucose in the presence of oxygen to produce ATP (energy), releasing carbon dioxide and water as byproducts.

> Photosynthesis is done by
→ Plants, algae, and some bacteria (autotrophs).

> Cellular respiration is done by
→ All living organisms (including plants, animals, fungi, and most bacteria).
