Photosynthesis

What are the raw materials needed for photosynthesis?

• Glucose and Oxygen

• Carbon dioxide and Glucose

• Carbon dioxide and Water

• Oxygen and Carbon dioxide

What type of reaction is photosynthesis?

• Endothermic

• Exothermic

• Chemothermic

• A plant reaction

What factors can affect the rate of photosynthesis?

• Light intensity and amount of oxygen

• Amount of oxygen and amount of chlorophyll

• Temperature and mineral ion concentration

• Light intensity and carbon dioxide concentration

How does a leaf get the carbon dioxide it needs?

• Osmosis through the roots

• Diffusion through the stomata

• Active transport through the leaves

• All of the above

How is the rate of photosynthesis measured?

• By measuring the time

• By measuring the CO2 produced

• By measuring the amount of glucose produced

• By measuring the amount of O2 produced in a given time

At higher temperatures, Enzymes become
