Photosynthesis and Factors

What are the three main factors that affect the rate of photosynthesis?

• Light intensity, carbon dioxide concentration, and temperature

• Nitrogen concentration, cloud cover, and time of day

• Wind speed, humidity, and soil type

• Water concentration, oxygen level, and soil pH

How does light intensity affect the rate of photosynthesis?

• Light intensity has no effect on the rate of photosynthesis

• The rate of photosynthesis is not affected by light intensity

• The rate of photosynthesis decreases with an increase in light intensity

• The rate of photosynthesis increases with an increase in light intensity

Explain how temperature affects the rate of photosynthesis.

• Enzyme activity is affected by temperature changes.

• Temperature has no impact on the rate of photosynthesis.

• Photosynthesis only occurs at extremely high temperatures.

• Temperature affects the color of the leaves, which in turn affects photosynthesis.

What is the role of carbon dioxide in the process of photosynthesis?

• It is used by plants to produce carbon monoxide and water through photosynthesis.

• It is used by plants to produce nitrogen and hydrogen through photosynthesis.

• It is used by plants to produce glucose and oxygen through photosynthesis.

• It has no role in the process of photosynthesis.

How does the availability of water impact the process of photosynthesis?

• Water is essential for the process of photosynthesis.

• Water inhibits the process of photosynthesis

• Photosynthesis can occur without water

• Water has no impact on photosynthesis
