Why do many plants appear green?

Chlorophyll absorbs red and blue light, reflecting green light.

Chlorophyll absorbs green light and reflects red and blue light.

Chlorophyll absorbs all wavelengths of light equally.

Chlorophyll reflects all light, making plants appear green.

What are the primary inputs required for the light-independent reactions (Calvin Cycle) of photosynthesis?

Fixed carbon dioxide, ATP, and NADPH

What is the role of chlorophyll?

The role of chlorophyll is to absorb light energy for photosynthesis.

Chlorophyll is responsible for water absorption.

Chlorophyll helps in nutrient storage in plants.

Chlorophyll is used for plant respiration.

What is the source of electrons for the light-dependent reactions of photosynthesis?

Water (H 2 O) is the source of electrons.

Carbon dioxide (CO 2 ) is the source of electrons.

Pick the correct statements about photosynthesis. .

The light reactions take place during the day.

The oxygen gas released comes from water.

The dark reactions take place at night.

The oxygen gas released comes from both water and carbon dioxide

What is the role of ATP in the Calvin cycle?

ATP serves as an energy source in the Calvin cycle.

ATP is a byproduct of the Calvin cycle.

What is the role of light in photosynthesis?

Light provides the energy required for the conversion of carbon dioxide and water into glucose and oxygen.

Light is a byproduct of photosynthesis.

Light is harmful to the process of photosynthesis.

Light is only needed for plant growth, not photosynthesis.

The Calvin cycle is also called the dark reaction because it does not need light energy, but it doesn't usually occur at night. Why?

The Calvin cycle depends on the products of the light reaction.

It is too cold for the reaction to take place.

CO 2 concentrations decrease at night.

Plants usually open their stomata at night.

What is the primary function of the Calvin cycle?

To convert carbon dioxide into glucose.

To break down glucose into carbon dioxide.

To absorb sunlight for photosynthesis.

In photosynthesis, what is ATP required for?

ATP is required for energy transfer in the Calvin cycle during photosynthesis.

ATP is used for oxygen production during photosynthesis.

What is the chemical equation of photosynthesis?

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

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

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

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