Photosynthesis KS2 Worksheet PDF (teacher made) - Twinkl - Free Printable

Problem Description:

The task involves completing a worksheet about photosynthesis. The worksheet includes filling in gaps, matching terms, and answering questions related to the process of photosynthesis.

Solution:

#### Part 1: Filling in the Gaps
The first section asks you to fill in the gaps using the words provided in the box. Here is the completed version:

Photosynthesis needs:
1. sunlight
2. carbon dioxide
3. water

Photosynthesis produces:
1. glucose
2. oxygen

So, the diagram should look like this:
```
+ water → glucose + oxygen
```

#### Part 2: Matching Terms
The second section asks you to match terms with their corresponding roles in photosynthesis. Here are the correct matches:

- producers: plants
- animals: consumers
- nutrients: growth
- chlorophyll: pigment

#### Part 3: Completing Sentences
The third section asks you to complete sentences about photosynthesis. Here are the answers:

1. Photosynthesis is essential for life on Earth and takes place in plants.
2. Green plants are producers. This means that they can survive without eating other organisms. They use simple things like sunlight, carbon dioxide, and water to make complex things like starch, fats, and proteins. When plants are in sunlight, they can make a lot of food.
3. Chlorophyll absorbs light energy in the chloroplasts. When plants use carbon dioxide and water to make glucose, there is a lot of energy stored in the glucose.

#### Part 4: Labeling the Diagram
The final part involves labeling a diagram of a leaf. While I cannot draw or label the diagram here, the key parts of a leaf involved in photosynthesis are typically:
- Stomata: Small pores on the underside of the leaf where gases (CO₂ and O₂) enter and exit.
- Chloroplasts: Organelles within plant cells containing chlorophyll, where photosynthesis occurs.
- Veins: Transport water and nutrients to the leaf cells.

Final Answer:

Here is the completed worksheet:

#### Filling in the Gaps:
```
+ water → glucose + oxygen

Photosynthesis needs:
1. sunlight
2. carbon dioxide
3. water

Photosynthesis produces:
1. glucose
2. oxygen
```

#### Matching Terms:
- producers: plants
- animals: consumers
- nutrients: growth
- chlorophyll: pigment
