Understanding Photosynthesis Processes

What is the primary function of photosynthesis?

• To convert light energy into chemical energy

• To produce oxygen for animals

• To absorb carbon dioxide from the atmosphere

• To create heat energy

Which of the following are the main reactants in the process of photosynthesis?

• Oxygen and glucose

• Carbon dioxide and water

• Nitrogen and water

• Glucose and sunlight

Identify the main products of photosynthesis.

• Carbon dioxide and water

• Oxygen and glucose

• Nitrogen and glucose

• Oxygen and carbon dioxide

Which part of the plant cell is primarily involved in photosynthesis?

• Mitochondria

• Chloroplast

• Nucleus

• Ribosome

What is the role of chlorophyll in photosynthesis?

• It absorbs sunlight

• It stores energy

• It releases oxygen

• It breaks down glucose

During the light-dependent reactions, what molecule is produced as a byproduct?

• Glucose

• Oxygen

• Carbon dioxide

• Water

In which part of the chloroplast do the light-dependent reactions occur?

• Stroma

• Thylakoid membrane

• Outer membrane

• Inner membrane

What is the main purpose of the light-independent reactions (Calvin cycle)?

• To produce ATP

• To produce glucose

• To release oxygen

• To absorb sunlight

Which of the following best describes the light-dependent reactions?

• They convert carbon dioxide into glucose

• They use sunlight to produce ATP and NADPH

• They occur in the stroma

• They do not require light

Which of the following equations correctly represents the overall process of photosynthesis?
