Understanding Photosynthesis and Plant Growth

Why do plants need sunlight?

• To grow taller

• To stay warm

• To change color

• To make their own food

What is photosynthesis?

• A technique for plants to grow roots

• A method for plants to drink water

• A way plants breathe

• A process where plants make food using sunlight

What do plants use to form new structures?

• Water and minerals

• Carbon dioxide and water

• Sunlight and soil

• Oxygen and nitrogen

What is a common misconception about plant food?

• That it is soil

• That it is water

• That it is made of sunlight

• That it comes in boxes

What do plants actually use to make their food?

• Water and minerals

• Carbon dioxide and water

• Sunlight and soil

• Oxygen and nitrogen

What is the special thing about food for plants?

• It only gives energy

• It makes them change color

• It only helps them grow taller

• It provides both energy and building materials

What is the main source of building materials for plants?

• Sunlight

• Water

• Soil

• Carbon dioxide

What is one way to help students understand how gases contribute to solids?

• By making them watch more documentaries

• By giving them plant food

• By teaching them about animal growth

• By showing examples like rust formation

What is the equation for photosynthesis?

• Oxygen + soil + light energy = glucose + carbon dioxide

• Carbon dioxide + water + light energy = glucose + oxygen

• Oxygen + water + light energy = glucose + carbon dioxide

• Carbon dioxide + soil + light energy = glucose + oxygen
