Define photosynthesis in your own words.

Write the balanced chemical equation for photosynthesis, including the necessary conditions.

List the four essential factors required for photosynthesis to occur.

What is the primary product of photosynthesis, and in what form is it temporarily stored in the leaves?

Describe a simple experiment to prove that light is necessary for photosynthesis. What observation would you expect?

How would you test a leaf for the presence of starch? Describe the steps and the expected positive result.

In an experiment to show that carbon dioxide is needed for photosynthesis, why is potassium hydroxide (KOH) solution often used?

What is the role of chlorophyll in photosynthesis?

Name the byproduct of photosynthesis that is essential for most living organisms.

Describe a simple setup to show that oxygen is released during photosynthesis using an aquatic plant like Hydrilla.

Why must a plant be "destarched" (kept in the dark for 48 hours) before conducting experiments on photosynthesis?

Explain the importance of photosynthesis in maintaining the balance of gases in the atmosphere.

What colours of light are most effectively absorbed by chlorophyll for photosynthesis?

How do terrestrial plants obtain the water and carbon dioxide needed for this process?

Explain why a variegated (green and white) leaf will only show a positive starch test in the green areas after being exposed to light.
