Understanding Photosynthesis Day and Night

What are the three essential ingredients plants need for photosynthesis during the day?

• Sunlight, oxygen, and glucose

• Sunlight, water, and carbon dioxide

• Water, oxygen, and nitrogen

• Carbon dioxide, glucose, and nitrogen

What is the role of chlorophyll in photosynthesis?

• It absorbs water from the soil

• It gives plants their green color and helps trap sunlight

• It releases oxygen into the air

• It converts glucose into energy

Which of the following is the correct chemical equation for photosynthesis?

What happens to the oxygen produced during photosynthesis?

• It is used by the plant for growth

• It is released into the air

• It is converted into glucose

• It is stored in the roots

What is the main product of photosynthesis that serves as food for the plant?

• Oxygen

• Carbon dioxide

• Glucose

• Water

During the night, what process do plants primarily rely on since photosynthesis cannot occur?

• Respiration

• Transpiration

• Fermentation

• Photosynthesis

Which part of the plant contains chlorophyll?

• Roots

• Stems

• Leaves

• Flowers

Why can't photosynthesis occur at night?

• There is no water available

• There is no carbon dioxide available

• There is no sunlight available

• The temperature is too low
