Photosynthesis Quiz

What is photosynthesis?

• The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigment, carbon dioxide, and water.

• The process by which green plants and some other organisms use moonlight to synthesize foods with the help of chlorophyll pigment, carbon dioxide, and water.

• The process by which green plants and some other organisms use sunlight to synthesize oxygen with the help of chlorophyll pigment, carbon dioxide, and water.

• The process by which green plants and some other organisms use sunlight to synthesize water with the help of chlorophyll pigment, carbon dioxide, and oxygen.

What are the two main stages of photosynthesis?

• light-dependent reactions and Calvin cycle

• dark-dependent reactions and Calvin cycle

• light-independent reactions and Krebs cycle

• chlorophyll-dependent reactions and glycolysis

Which part of the plant cell is responsible for photosynthesis?

• chloroplast

• cell membrane

• mitochondria

• nucleus

What is the primary pigment involved in photosynthesis?

• carbon dioxide

• water

• chlorophyll

What is the role of light in photosynthesis?

• Light provides the energy for photosynthesis.

• Light is a byproduct of photosynthesis.

• Light is used to transport water in plants.

• Light is responsible for the production of oxygen in photosynthesis.

What are the products of the light-dependent reactions?

• Glucose and Oxygen

• ADP and NADP+

• ATP and FADH2

• ATP and NADPH

What is another name for the light-independent reactions of photosynthesis?

• Electron transport chain

• Glycolysis

• Krebs cycle

• Calvin cycle

What factors can affect the rate of photosynthesis?

• Soil pH, wind speed, and humidity.

• Leaf color, plant height, and flower size.

• Animal activity, soil fertility, and air pollution.

• Light intensity, temperature, carbon dioxide concentration, water availability, and nutrient availability.

How does temperature affect photosynthesis?

• Temperature has no effect on photosynthesis

• Temperature increases the efficiency of photosynthesis

• Temperature affects the rate of photosynthesis

• Temperature decreases the rate of photosynthesis

What is the equation for photosynthesis?

• 6CO2 + 6H2O + heat energy → C6H12O6 + 6O2

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

• 6CO2 + 6H2O + glucose → C6H12O6 + 6O2

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2
