Interactive worksheet for students to drag and drop terms like photosynthesis, respiration, glucose, carbon dioxide, oxygen, water, light energy, and ATP energy into the correct places on a diagram of cellular processes.

Let’s work through this step by step.

We’re looking at a diagram that shows how two key processes in living things — photosynthesis and respiration — are connected. These processes involve organelles (special parts inside cells): the green one is a chloroplast (does photosynthesis), and the blue one is a mitochondrion (does respiration).

The diagram has arrows showing what goes in and out of each process, and we need to match the correct terms from the list:

> Photosynthesis, Respiration, Glucose, Carbon Dioxide, Oxygen, Water, Light Energy, ATP Energy

---

Step 1: Look at the top part — the green organelle (chloroplast). It gets input from the sun (yellow starburst with wavy arrow) → that’s Light Energy.

So, the box pointing to the chloroplast from the sun should be: Light Energy

---

Step 2: The chloroplast also takes in gases and liquids from the cycle. From the left side, there’s an orange arrow coming from a “gas” box → that must be Carbon Dioxide, because plants take in CO₂ for photosynthesis.

And another orange arrow from a “liquid” box → that’s Water, since plants use water in photosynthesis too.

So:
- “gas” on the left → Carbon Dioxide
- “liquid” → Water

---

Step 3: What does the chloroplast produce? It makes sugar (glucose) and releases oxygen as a gas.

Looking at the right side:
- There’s a green arrow going down labeled “sugar” → that’s Glucose
- Another green arrow labeled “gas” → that’s Oxygen

So:
- “sugar” box → Glucose
- “gas” on the right → Oxygen

---

Step 4: Now look at the bottom — the blue organelle (mitochondrion). It uses glucose and oxygen to make energy.

It takes in:
- Glucose (from the top right)
- Oxygen (from the right side)

And it produces:
- A burst of energy (red starburst) → that’s ATP Energy (the energy currency of cells)
- And it releases carbon dioxide and water as waste — which go back to the chloroplast!

Also, the process happening in the mitochondrion is called Respiration.

So:
- The box under the mitochondrion → Respiration
- The red burst → ATP Energy

---

Step 5: What’s the process happening in the chloroplast? That’s Photosynthesis.

There’s a box above the chloroplast — that should be Photosynthesis

---

Now let’s map all boxes:

Top box (above chloroplast): Photosynthesis

Box from sun to chloroplast: Light Energy

Left “gas” box: Carbon Dioxide

Left “liquid” box: Water

Right “gas” box (output from chloroplast): Oxygen

Right “sugar” box: Glucose

Bottom box (under mitochondrion): Respiration

Red burst near mitochondrion: ATP Energy

Wait — let’s double-check if we used all 8 terms:

Used:
1. Photosynthesis ✔
2. Respiration ✔
3. Glucose ✔
4. Carbon Dioxide ✔
5. Oxygen ✔
6. Water ✔
7. Light Energy ✔
8. ATP Energy ✔

Perfect — all accounted for.

Final matching:

- Top box (above chloroplast): Photosynthesis
- Box from sun: Light Energy
- Left “gas”: Carbon Dioxide
- Left “liquid”: Water
- Right “gas”: Oxygen
- Right “sugar”: Glucose
- Bottom box (under mitochondrion): Respiration
- Red burst: ATP Energy

---

Final Answer:
Photosynthesis → top box
Light Energy → from sun to chloroplast
Carbon Dioxide → left gas box
Water → left liquid box
Oxygen → right gas box
Glucose → right sugar box
Respiration → bottom box under mitochondrion
ATP Energy → red burst near mitochondrion
