Photosynthesis Worksheet | PDF - Free Printable

Let's solve the problem step by step using the image and the words provided at the bottom of the page.

Step 1: Understand the diagram

The diagram shows:
- Sunlight (light) shining on a plant.
- Carbon dioxide entering the plant from the air.
- Water being absorbed by the roots from the soil.
- Oxygen being released into the air.
- Sugar is formed inside the plant as food.

This represents the process of photosynthesis, where plants make their own food.

Step 2: Recall the photosynthesis equation

Photosynthesis can be summarized as:

> Light energy + Carbon dioxide + Water → Sugar + Oxygen

So, plants use:
- Light from the sun,
- Carbon dioxide from the air,
- Water from the soil,

to produce:
- Sugar (food for the plant),
- And release oxygen into the air.

Step 3: Fill in the blanks

Now, let’s go through the sentence:

> "Photosynthesis is a process where plants use ________ from the sun to convert ________ from the air and ________ from the soil into ________ to feed the plant and ________ is given out in the air."

Using the words:
water, sugar, carbon dioxide, light, oxygen

We fill in:

1. light – from the sun
2. carbon dioxide – from the air
3. water – from the soil
4. sugar – to feed the plant
5. oxygen – is given out in the air

Final Answer:

> Photosynthesis is a process where plants use light from the sun to convert carbon dioxide from the air and water from the soil into sugar to feed the plant and oxygen is given out in the air.

✔ This matches the diagram and the scientific understanding of photosynthesis.
