To solve this worksheet, we need to understand the chemical process of photosynthesis.
Step 1: Identify the Inputs (Reactants)
Photosynthesis is how plants make their own food. To do this, they need three main things coming in from the outside world:
1.
Sunlight: The image shows a sun shining on the plant. This provides the energy needed for the reaction.
2.
Water ($H_2O$): Plants absorb water through their roots.
3.
Carbon Dioxide ($CO_2$): Plants take this gas in from the air through their leaves.
Looking at the left side of the diagram, there are three empty boxes with plus signs between them. These represent the ingredients. So, the three boxes should be filled with:
* Sunlight (or Light Energy)
* Water
* Carbon Dioxide
Step 2: Identify the Outputs (Products)
The green arrow points to the right, showing what the plant produces after using the inputs.
1.
Glucose: One box already says "Glucose." This is the sugar/food the plant makes.
2.
Oxygen ($O_2$): As a byproduct of making glucose, plants release oxygen into the air. This is the second box on the right.
Step 3: Answering the Question "How does Photosynthesis work?"
This section asks for a written explanation. We can summarize the process based on the boxes we just filled out.
* Plants use sunlight to turn carbon dioxide and water into glucose and oxygen.
* It happens inside the leaves.
* The equation is often written as: $Carbon Dioxide + Water + Sunlight \rightarrow Glucose + Oxygen$.
Summary of the blanks:
*
Left Side (Inputs): Sunlight, Water, Carbon Dioxide (Order doesn't strictly matter, but usually listed together).
*
Right Side (Outputs): Glucose (given), Oxygen.
*
Writing Section: Explain that plants use light energy to convert water and carbon dioxide into food (glucose) and release oxygen.
Final Answer:
Left Boxes (Inputs):
1. Sunlight (Light Energy)
2. Water
3. Carbon Dioxide
Right Box (Output):
1. Oxygen
"How does Photosynthesis work?" Answer:
Plants use energy from sunlight to mix water (absorbed from roots) and carbon dioxide (taken from air). This process creates glucose (sugar) which gives the plant food/energy, and releases oxygen as a waste product.
