Understanding Photosynthesis Misconceptions

Which part of the plant cell is responsible for capturing light energy during photosynthesis?

• Mitochondria

• Chloroplast

• Nucleus

• Cell wall

What is the main reason leaves appear green to our eyes?

• They absorb green light and reflect all others

• They reflect green light and absorb other wavelengths

• They contain green-coloured water

• They do not absorb any light

Which gas do plants take in from the atmosphere for photosynthesis?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What is the main role of light in photosynthesis?

• To provide heat for the plant

• To break down glucose

• To provide energy to convert carbon dioxide and water into glucose

• To help the plant breathe

Which of the following is a correct word equation for photosynthesis?

• Glucose + Oxygen → Carbon dioxide + Water

• Carbon dioxide + Water → Glucose + Oxygen

• Oxygen + Water → Carbon dioxide + Glucose

• Carbon dioxide + Glucose → Water + Oxygen

Where does the carbon dioxide used in photosynthesis come from?

• The soil

• The air

• The plant’s roots

• The sun

Which statement best describes the relationship between photosynthesis and respiration in plants?

• Photosynthesis and respiration are the same process

• Photosynthesis stores energy, respiration releases it

• Respiration only happens at night, photosynthesis only during the day

• Respiration produces glucose, photosynthesis uses it

Why do plants need chlorophyll for photosynthesis?

• It absorbs water from the soil

• It absorbs light energy needed for the reaction

• It stores glucose

• It helps the plant grow roots

Which of the following is NOT a product of photosynthesis?

• Glucose

• Oxygen

• Carbon dioxide

• Energy stored in glucose

If a plant is kept in the dark, what will happen to its rate of photosynthesis?

• It will increase

• It will decrease

• It will stay the same

• It will produce more oxygen
