Step-by-step solution for: Factors Affecting Photosynthesis Gap Fill Worksheet | Beyond
It looks like you've uploaded an image of a worksheet on photosynthesis, which includes fill-in-the-blank questions and a word bank. While I can't directly view or analyze the image, I can help you solve the task based on standard photosynthesis knowledge and typical content found in such worksheets.
Let me walk through what this worksheet likely contains and provide a complete solution with explanations.

Photosynthesis is the process by which green plants (and some other organisms) use sunlight to convert carbon dioxide and water into glucose (a sugar) and oxygen. This process occurs mainly in the chloroplasts of plant cells.
---
- Photosynthesis: The process where plants make their own food using light energy.
- Chlorophyll: Green pigment in chloroplasts that absorbs light energy.
- Reactants: Carbon dioxide + Water → Glucose + Oxygen
- Products: Glucose (food for the plant), Oxygen (released into the air)
- Location: Chloroplasts in plant cells
- Factors affecting rate: Light intensity, carbon dioxide concentration, temperature
---
#### Part 1: Fill in the blanks using the word bank
Word Bank:
carbon dioxide, chloroplasts, energy, glucose, increase, leaves, light, reactants, roots, photosynthesis, rate, reactants, temperature, water

1. Plants are known as __________ because they are able to make their own food using __________ from the Sun. They do this via a process called __________. This process mainly takes place in the __________ of a plant.
✔ Answer:
Plants are known as producers because they are able to make their own food using light from the Sun. They do this via a process called photosynthesis. This process mainly takes place in the leaves of a plant.
> 💡 *Explanation:* Producers create their own food; light is the energy source; photosynthesis is the process; leaves have many chloroplasts for efficient light absorption.
---
2. The reaction can be summarised in the word equation below:
__________ + __________ → __________ + __________
✔ Answer:
Carbon dioxide + Water → Glucose + Oxygen
> 💡 *Explanation:* These are the inputs (reactants) and outputs (products) of photosynthesis.
---
3. The reaction takes place in the __________. These structures contain a green pigment called chlorophyll, which absorbs __________. The energy absorbed is used to convert carbon dioxide and water into glucose and oxygen.
✔ Answer:
The reaction takes place in the chloroplasts. These structures contain a green pigment called chlorophyll, which absorbs light.
> 💡 *Explanation:* Chloroplasts are organelles in plant cells where photosynthesis occurs. Chlorophyll captures light energy.
---
4. If light is not available, photosynthesis cannot occur. When light is available, the rate of photosynthesis increases. However, if the light intensity is too high, the rate will not increase further.
✔ Answer:
If light is not available, photosynthesis cannot occur. When light is available, the rate of photosynthesis increases. However, if the light intensity is too high, the rate will not increase further.
> 💡 *Explanation:* Light is a limiting factor. Beyond a certain point, other factors (like CO₂ or temperature) become limiting.
---
5. The rate of photosynthesis also depends on:
- Carbon dioxide concentration: Higher levels → higher rate (up to a point).
- Temperature: Optimal range (around 25–35°C). Too cold = slow enzymes. Too hot = denatures enzymes.
- Water availability: Needed as a reactant. Drought reduces photosynthesis.
✔ So, increasing carbon dioxide, light intensity, or temperature (within limits) will increase the rate of photosynthesis.

| Blank | Answer |
|-------|--------|
| 1. Plants are known as... | producers |
| 2. Using... from the Sun | light |
| 3. Process called... | photosynthesis |
| 4. Takes place in the... | leaves |
| 5. Word equation: | Carbon dioxide + Water → Glucose + Oxygen |
| 6. Reaction takes place in... | chloroplasts |
| 7. Chlorophyll absorbs... | light |
| 8. Rate increases with... | increase |
---
- Remember: "CO₂ + H₂O → C₆H₁₂O₆ + O₂" – this is the chemical equation.
- Use the mnemonic: "Light Energy → Food!"
- Factors affecting rate: Light, CO₂, Temperature (the three main ones).
