Q: What is photosynthesis?
A: Photosynthesis is the process by which plants make their own food using sunlight, water, and carbon dioxide.

Q: What do plants need for photosynthesis?
A: Plants need sunlight, water, and carbon dioxide.

Q: What do plants produce during photosynthesis?
A: Plants produce oxygen and food (glucose).

Q: Which part of the plant helps in photosynthesis?
A: The leaves help in photosynthesis.

Q: What gives leaves their green color?
A: Chlorophyll, a green pigment in leaves, gives them their color.

Q: What is the role of the sun in photosynthesis?
A: The sun provides energy for the plant to make food.

Q: Where do plants get carbon dioxide from?
A: Plants get carbon dioxide from the air through tiny openings in their leaves called stomata.

Q: Where do plants get water from?
A: Plants absorb water from the soil through their roots.

Q: What do plants release into the air during photosynthesis?
A: Plants release oxygen into the air.

Q: Why is photosynthesis important for humans and animals?
A: Photosynthesis produces oxygen, which humans and animals need to breathe, and food, which they eat.

Q: When does photosynthesis take place?
A: Photosynthesis takes place during the daytime when sunlight is available.

Q: What happens if there is no sunlight for a long time?
A: If there is no sunlight, plants cannot make food, and they may die.

Q: Can plants make food without water?
A: No, plants need water for photosynthesis to make food.

Q: How does photosynthesis help keep the air clean?
A: Plants take in carbon dioxide and give out oxygen, which helps keep the air clean and fresh.

Q: What would happen if there were no plants on Earth?
A: If there were no plants, there would be no oxygen for humans and animals to breathe, and no food for many living things.
