Photosynthesis for 6th Graders

What is photosynthesis?

• The process by which green plants use sunlight to synthesize food

• The process by which clouds use sunlight to synthesize food

• The process by which animals use sunlight to synthesize food

• The process by which rocks use sunlight to synthesize food

What are the two main raw materials needed for photosynthesis?

• Glucose and chlorophyll

• Oxygen and nitrogen

• Sunlight and soil

• Carbon dioxide and water

Where does photosynthesis take place in a plant cell?

• Mitochondria

• Chloroplasts

• Cell membrane

• Nucleus

What is the role of chlorophyll in photosynthesis?

• Absorbs light energy for photosynthesis

• Converts carbon dioxide into oxygen

• Regulates the temperature for photosynthesis

• Reflects light energy for photosynthesis

What are the two main products of photosynthesis?

• Nitrogen and hydrogen

• Carbon dioxide and water

• Glucose and oxygen

• Methane and nitrogen dioxide

What is the chemical equation for photosynthesis?

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 4CO2 + 4H2O → C4H8O4 + 4O2

• 6CO2 + 6H2O → C6H12O6 + 6O2

• 2H2O + 2CO2 → 2H2CO3 + O2

What is the importance of photosynthesis for plants and other living organisms?

• It has no importance for plants and other living organisms.

• It produces oxygen and glucose, which are essential for their survival.

• It produces carbon dioxide and water, which are harmful for their survival.

• It creates darkness and reduces the amount of sunlight available for plants.

What are the environmental factors that can affect the rate of photosynthesis?

• Nitrogen levels, cloud cover, and air pressure

• Sun angle, ozone levels, and precipitation

• Light intensity, temperature, water, and carbon dioxide

• Wind speed, soil pH, and humidity

How does photosynthesis contribute to the oxygen cycle?

• Photosynthesis absorbs oxygen from the atmosphere.

• Photosynthesis releases carbon dioxide into the atmosphere.

• Photosynthesis converts carbon dioxide into nitrogen gas.

• Photosynthesis produces oxygen as a byproduct.

Explain the process of photosynthesis in simple terms.

• Plants use sunlight, oxygen, and water to make food.

• Plants use sunlight, nitrogen, and water to make food.

• Plants use sunlight, carbon dioxide, and water to make food.

• Plants use moonlight, carbon dioxide, and water to make food.
