Photosynthesis Quiz

What is the process by which plants use the energy from light to convert carbon dioxide and water into carbohydrates and oxygen?

• Respiration

• Photosynthesis

• Fermentation

• Digestion

Where does photosynthesis primarily take place within the leaves of plants?

• Stomata

• Xylem

• Chloroplasts in the palisade cells

• Phloem

What is the main purpose of the carbohydrates produced during photosynthesis?

• To provide energy for growth through respiration

• To be released into the atmosphere

• To be used in the process of digestion

• To be stored in the stomata

What are the two stages of photosynthesis?

• Light stage and Dark stage

• Day stage and Night stage

• Energy stage and Growth stage

• Carbon stage and Oxygen stage

What happens during the light stage of photosynthesis?

• Carbohydrates are stored as starch

• Water molecules are split to release hydrogen

• Carbon dioxide is absorbed from the atmosphere

• Oxygen is released through the stomata

Which factor is considered the most significant in affecting the rate of photosynthesis?

• Temperature

• Water availability

• Light intensity

• Carbon dioxide levels

What is the optimum temperature range for photosynthesis?

• 10-20°C

• 25-35°C

• 40-50°C

• 15-25°C

What happens to the stomata if there is insufficient water available in the plant?

• They open wider

• They close and inhibit photosynthesis

• They release more oxygen

• They increase carbon dioxide intake

Which of the following is NOT a factor affecting the rate of photosynthesis?

• Light intensity

• Temperature

• Water availability

• Oxygen levels

What is the basic process that captures energy from the sun and utilizes it for building living things?

• Respiration

• Photosynthesis

• Fermentation

• Digestion
