The Magic of Photosynthesis and Cellular Respiration

What do plants use to make their own food?

• Water, sunlight, and carbon dioxide

• Soil, water, and sunlight

• Soil and water only

• Sunlight and air gases only

What is the main purpose of photosynthesis?

• To make food for the plant

• To absorb water from the soil

• To create food for animals

• To produce oxygen for humans

What is not a product of the photosynthesis process?

• Carbon dioxide

• Glucose

• Oxygen

• Water

Why do plants perform photosynthesis?

• To absorb water

• To grow

• To produce oxygen

• To breathe

Where do the light-dependent reactions of photosynthesis occur?

• In the nucleus

• In the chloroplasts

• On the leaf surface

• In the mitochondria

How do humans participate in the photosynthesis process?

• By providing carbon dioxide

• By capturing sunlight

• By absorbing oxygen

• By supplying water

What do plants not need during the light-independent reactions?

• Water

• Carbon dioxide

• Sunlight

• Chlorophyll

What is not a fate of glucose in plants?

• Storing as starch

• Creating chlorophyll

• Building cellulose

• Making ATP

What is the main construction material for plant cells?

• Cellulose

• Sucrose

• Starch

• Glucose

What is cellular respiration?

• A process to make food

• A process to capture sunlight

• A process to produce oxygen

• A process to release energy from food
