Photosynthesis

Which part of the plant collects the sun's energy?

• The Root

• The Stem

• The Leaf

• The Flower

How do plants take in carbon dioxide?

• Through their roots

• Through small openings in their leaves called stomata

• By absorbing it through their flowers

• By releasing oxygen into the air

What is the main product of photosynthesis?

• Oxygen

• Glucose

• Carbon Dioxide

• Water

What gas do plants take in before photosynthesis?

• Oxygen

• Nitrogen

• Carbon Dioxide

• Hydrogen

What is the relationship between photosynthesis and respiration?

• Photosynthesis produces carbon dioxide and water, which are used in respiration to release energy.

• Photosynthesis produces oxygen and glucose, which are used in respiration to release energy.

• Photosynthesis and respiration are unrelated processes that occur in plants.

• Photosynthesis occurs only at night, while respiration occurs during the day.

What happens to the oxygen produced during photosynthesis?

• It is absorbed by the roots of the plant.

• It is released into the air.

• It is converted into glucose.

• It is stored in the leaves for later use.

What is chlorophyll?

• A type of carbohydrate found in plants

• The green pigment in plants that absorbs sunlight for photosynthesis

• A mineral essential for plant growth

• A hormone that regulates plant growth

What is NOT an impact of photosynthesis on an ecosystem?

• Taking oxygen out of the air

• Producing glucose for energy

• Releasing oxygen into the atmosphere

• Providing food for herbivores

How does water contribute to photosynthesis?

• Water is a waste product of photosynthesis.

• Water is one of the essential ingredients that plants need to perform photosynthesis.

• Water helps in the absorption of sunlight.

• Water is not involved in the process of photosynthesis.

Why is photosynthesis important for animals?

• It provides food for animals.

• It produces oxygen for them to breathe.

• It helps animals to reproduce.

• It regulates animal body temperature.
