Photosynthesis Diagram online exercise for - Free Printable

The image provided is a worksheet about photosynthesis, a fundamental process in biology. Below is the solution and explanation for filling out the diagram:

---

1. Photosynthesis Equation

The general equation for photosynthesis is:
\[ \text{Carbon Dioxide (CO}_2\text{)} + \text{Water (H}_2\text{O)} + \text{Light Energy} \rightarrow \text{Glucose (C}_6\text{H}_{12}\text{O}_6\text{)} + \text{Oxygen (O}_2\text{)} \]

So, the blanks in the equation should be filled as follows:
- Left side: \( \text{CO}_2 \) and \( \text{H}_2\text{O} \)
- Right side: \( \text{C}_6\text{H}_{12}\text{O}_6 \) and \( \text{O}_2 \)

Thus, the completed equation is:
\[ \text{CO}_2 + \text{H}_2\text{O} + \text{Light Energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2 \]

2. Components of the Diagram

#### Top Left (Sun Icon):
This represents the source of light energy required for photosynthesis. The blank box next to it should be labeled:
- Light Energy

#### Bottom Left (Plant Roots and Soil):
This represents the source of water (H₂O) for photosynthesis. The roots absorb water from the soil. The blank box next to it should be labeled:
- Water (H₂O)

#### Bottom Center (Plant Leaves):
This is where photosynthesis occurs, specifically in the chloroplasts (the green structures shown inside the leaf). The blank box next to it should be labeled:
- Chloroplasts

#### Top Right (Human Lungs):
This represents the source of carbon dioxide (CO₂), which plants absorb from the air. The blank box next to it should be labeled:
- Carbon Dioxide (CO₂)

#### Right Side (Molecule Image):
This represents the product of photosynthesis, which is glucose (\( \text{C}_6\text{H}_{12}\text{O}_6 \)). The blank box next to it should be labeled:
- Glucose (C₆H₁₂O₆)

#### Far Right (Oxygen Molecule):
This represents the byproduct of photosynthesis, which is oxygen (\( \text{O}_2 \)). The blank box next to it should be labeled:
- Oxygen (O₂)

3. Purpose of Photosynthesis

The purpose of photosynthesis is to:
- Convert light energy into chemical energy stored in glucose.
- Provide energy for the plant's growth and survival.
- Release oxygen as a byproduct, which is essential for aerobic respiration in animals and humans.

The blank at the bottom should be filled with:
- To produce glucose for energy and release oxygen as a byproduct.

---

Final Filled Diagram:

- Top left: Light Energy
- Bottom left: Water (H₂O)
- Bottom center: Chloroplasts
- Top right: Carbon Dioxide (CO₂)
- Right side: Glucose (C₆H₁₂O₆)
- Far right: Oxygen (O₂)
- Bottom arrow: The purpose of photosynthesis is to produce glucose for energy and release oxygen as a byproduct.

Completed Equation:

\[ \text{CO}_2 + \text{H}_2\text{O} + \text{Light Energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2 \]

---

Final Answer:

\[
\boxed{
\text{Light Energy, Water (H}_2\text{O), Chloroplasts, Carbon Dioxide (CO}_2\text{), Glucose (C}_6\text{H}_{12}\text{O}_6\text{), Oxygen (O}_2\text{), To produce glucose for energy and release oxygen as a byproduct.}
