Photosynthesis Practice Practice Problems

Grades 5-9 · 5 problems

Practice your knowledge of photosynthesis with these problems. Understand how plants use sunlight, water, and carbon dioxide to create energy.

Tip: Photosynthesis is how plants convert light energy into chemical energy in the form of glucose, which they use as food.
1

What are the two main products of photosynthesis?

2

What is the primary pigment in plants that absorbs light energy for photosynthesis?

3

What gas do plants take in from the atmosphere to perform photosynthesis?

4

Where in the plant cell does photosynthesis primarily occur?

5

If a plant is placed in a sealed container with a limited supply of carbon dioxide, how will the rate of photosynthesis be affected over time?

Common Mistakes

  • Confusing photosynthesis with respiration.
  • Thinking plants only perform photosynthesis during the day.
  • Forgetting that water is a key ingredient for photosynthesis.
