RP Photosynthesis

What is the relationship between light intensity and the rate of photosynthesis in the experiment?

• As light intensity decreases, the rate of photosynthesis increases
• As light intensity increases, the rate of photosynthesis remains constant
• As light intensity increases, the rate of photosynthesis decreases
• As light intensity decreases, the rate of photosynthesis decreases

What term is used to describe the phenomenon where doubling the distance from the light source causes the light intensity to fall by four times?

• The exponential growth law
• The inverse square law
• The square root law
• Direct proportionality

Why is a beaker of water placed between the light and the boiling tube when using a normal light bulb?

• To release carbon dioxide needed for photosynthesis
• To prevent temperature changes in the experiment
• To absorb heat produced by the bulb
• To provide light for photosynthesis

What is the purpose of using sodium bicarbonate in the photosynthesis experiment setup?

• To provide additional light for photosynthesis
• To absorb excess oxygen produced
• To prevent temperature changes in the experiment
• To release carbon dioxide needed for photosynthesis

Why is it better to measure the volume of oxygen produced instead of counting bubbles in the experiment?

• To speed up the experiment process
• To ensure accurate data collection
• To reduce the number of repetitions needed
• To simplify the experimental setup

What gas is produced by photosynthesis in the experiment?

• Nitrogen
• Carbon dioxide
• Oxygen
• Hydrogen
