Plant Photosynthesis

Explain the process of photosynthesis in plants.

• Plants use sunlight, water, and carbon dioxide to produce glucose and oxygen in the chloroplasts.

• Plants use moonlight, water, and carbon dioxide to produce glucose and oxygen in the chloroplasts.

• Plants use sunlight, water, and oxygen to produce glucose and carbon dioxide in the chloroplasts.

• Plants use sunlight, nitrogen, and carbon dioxide to produce glucose and oxygen in the mitochondria.

What are the two main stages of photosynthesis?

• Dark reactions and Krebs cycle

• Photosystem I and Photosystem II

• Stroma and Thylakoid membrane

• Light reactions and Calvin cycle

How does light intensity affect the rate of photosynthesis?

• High light intensity decreases the rate of photosynthesis

• Photosynthesis occurs faster in the absence of light

• Light intensity has no impact on photosynthesis

• Light intensity affects the rate of photosynthesis by providing the energy needed for the process to occur.

Discuss the role of carbon dioxide in the process of photosynthesis.

• Carbon dioxide is only used by animals in the process of photosynthesis

• Plants use carbon dioxide to produce water in photosynthesis

• Carbon dioxide is used by plants in photosynthesis to produce glucose and oxygen.

• Carbon dioxide is a byproduct of photosynthesis

What are some factors that can limit the rate of photosynthesis in plants?

• Low temperatures

• Insufficient light intensity, low carbon dioxide levels, high temperatures, water stress, limited availability of nutrients

• High carbon dioxide levels

• Excessive light intensity
