Understanding Photosynthesis

What is the primary role of photosynthesis in plants?

• To produce oxygen for animals

• To convert sunlight into chemical energy

• To absorb carbon dioxide from the atmosphere

• To provide shade

How does photosynthesis contribute to the cycling of matter?

• By converting glucose into sunlight

• By releasing nitrogen into the atmosphere

• By exchanging carbon dioxide and oxygen between plants and animals

• By producing water as a byproduct

What happens to the oxygen produced during photosynthesis?

• It is converted into glucose

• It is stored in the roots of plants

• It is released into the atmosphere for animals to breathe

• It is used by plants for growth

What is the source of energy for photosynthesis?

• Glucose

• Water

• Sunlight

• Carbon dioxide

How do animals benefit from the glucose produced by plants?

• It provides them with energy for daily activities

• It gives them water

• It helps them breathe

• It allows them to photosynthesize
