Question

1. how does the distance of the light affect the rate of photosynthesis? summarize the results with a three sentence cer (one complete sentence for each part).

claim: ?
evidence: ?
reasoning: ?

1. what do you think would happen to the number of bubbles produced by the plant if the bulb was switched off? why? 2.

Explanation:

For Question 1:

• Claim: The distance of light from a plant inversely affects the photosynthesis rate.
• Evidence: Experiments show plants closer to light produce more oxygen bubbles (a photosynthesis byproduct) than those farther away.
• Reasoning: Light is a key reactant for photosynthesis; closer light means higher light intensity, which speeds up the reaction, increasing bubble production.

For Question 2:

When the bulb is switched off, the plant loses its light source, which is essential for the light-dependent reactions of photosynthesis. Without light, photosynthesis stops, so no oxygen gas (which forms the bubbles) is produced.

Answer:

1.
Claim: The distance of light inversely impacts photosynthesis rate.
Evidence: Plants closer to light generate more oxygen bubbles than distant ones.
Reasoning: Closer light = higher intensity, speeding up photosynthesis.

1. The number of bubbles would drop to zero. Photosynthesis requires light as a critical input; without it, the process stops, so no oxygen (the gas in the bubbles) is produced.
