Let’s work through this step by step.
This worksheet is about
cellular respiration and
photosynthesis, and how they are connected. You’re supposed to fill in the blanks using words from the “Word Bank” boxes.
There are two main processes shown:
1.
Photosynthesis (done by plants, uses sunlight)
2.
Cellular Respiration (done by all living things, makes energy)
They form a cycle — the products of one become the reactants of the other.

Step 1: Look at the top part — Photosynthesis
The green organelle shown is the
chloroplast (where photosynthesis happens).
In photosynthesis:
- Reactants = Carbon Dioxide + Water + Sunlight
- Products = Glucose + Oxygen
So, on the diagram:
→ The arrow pointing *into* the chloroplast should be labeled with
Reactants: Carbon Dioxide, Water, Sunlight
→ The arrow pointing *out* should be labeled with
Products: Glucose, Oxygen
Also, the organelle name =
Chloroplast
Process name =
Photosynthesis

Step 2: Look at the bottom part — Cellular Respiration
The orange/brown organelle shown is the
mitochondrion (where cellular respiration happens).
In cellular respiration:
- Reactants = Glucose + Oxygen
- Products = Carbon Dioxide + Water + ATP (energy)
So, on the diagram:
→ Arrow pointing *into* mitochondrion =
Reactants: Glucose, Oxygen
→ Arrow pointing *out* =
Products: Carbon Dioxide, Water, ATP
Organelle name =
Mitochondrion
Process name =
Cellular Respiration

Step 3: Match the Word Banks
Top Word Bank has:
- Mitochondria
- Photosynthesis
- Chloroplast
- Cellular Respiration
- Carbon Dioxide
- Oxygen
- Water
- Glucose
- Sunlight
- ATP
Bottom Word Bank has:
- Carbon Dioxide
- Oxygen
- Glucose
- Water
- Sunlight
- ATP
We’ll use these to fill in the blanks.

Filling in the Diagram:
#### Top Section (Photosynthesis):
- Organelle:
Chloroplast
- Process:
Photosynthesis
- Reactants (going in):
Carbon Dioxide, Water, Sunlight
- Products (coming out):
Glucose, Oxygen
#### Bottom Section (Cellular Respiration):
- Organelle:
Mitochondrion (or Mitochondria — both acceptable)
- Process:
Cellular Respiration
- Reactants (going in):
Glucose, Oxygen
- Products (coming out):
Carbon Dioxide, Water, ATP
Note: The arrows between the two processes show that the products of one become the reactants of the other — that’s the cycle!

✔ All parts are now filled logically based on biology facts.
Final Answer:
Top: Chloroplast, Photosynthesis, Reactants: Carbon Dioxide, Water, Sunlight; Products: Glucose, Oxygen
Bottom: Mitochondrion, Cellular Respiration, Reactants: Glucose, Oxygen; Products: Carbon Dioxide, Water, ATP
Parent Tip: Review the logic above to help your child master the concept of cellular respiration and photosynthesis worksheet.
