Photosynthesis

How do plants store energy produced during photosynthesis?

• As glucose

• As starch

• As proteins

• As fats

What gas do plants release during photosynthesis?

• Carbon Dioxide

• Oxygen

• Nitrogen

• Hydrogen

What happens to the rate of photosynthesis if daylight hours decrease?

• The rate of photosynthesis increases.

• The rate of photosynthesis remains the same.

• The rate of photosynthesis decreases.

• The rate of photosynthesis fluctuates.

What gas do plants take in during photosynthesis?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What are the products of photosynthesis?

• Glucose and oxygen

• Carbon dioxide and water

• Nitrogen and glucose

• Oxygen and nitrogen

What is chlorophyll?

• A type of carbohydrate found in plants

• The green pigment in plants that absorbs light energy for photosynthesis

• A mineral essential for plant growth

• A hormone that regulates plant growth

What is the difference between autotrophs and heterotrophs?

• Autotrophs produce their own food, while heterotrophs consume other organisms for energy.

• Autotrophs are animals, while heterotrophs are plants.

• Autotrophs can only survive in water, while heterotrophs can survive on land.

• Autotrophs require sunlight, while heterotrophs do not.

What do plants use glucose for?

• For photosynthesis only

• For energy, growth, making new cells, and storing for later use

• To produce oxygen

• To absorb water from the soil

What role does water play in photosynthesis?

• Water is a byproduct of photosynthesis.

• Water is a raw material in photosynthesis; it is split to provide electrons and protons for the formation of glucose.

• Water is used to absorb sunlight during photosynthesis.

• Water helps in the transportation of nutrients in plants.

What is an autotroph?

• An organism that can produce its own food from inorganic substances using light or chemical energy.

• An organism that consumes other organisms for energy.

• An organism that relies solely on organic substances for food.

• An organism that can survive without any energy source.
