Understanding Photosynthesis Basics

What is the primary purpose of photosynthesis in plants?

• To produce carbon dioxide

• To produce glucose and oxygen

• To absorb nutrients from the soil

• To generate heat

Which organelle is primarily involved in the process of photosynthesis?

• Mitochondria

• Nucleus

• Chloroplast

• Ribosome

What pigment is responsible for capturing light energy in plants?

• Carotene

• Xanthophyll

• Chlorophyll

• Anthocyanin

In which part of the chloroplast do the light reactions of photosynthesis occur?

• Stroma

• Thylakoid membrane

• Outer membrane

• Inner membrane

What is the first stage of photosynthesis?

• Calvin Cycle

• Light reactions

• Glycolysis

• Krebs Cycle

Which molecule is split to release oxygen during the light reactions?

• ATP

What is the main product of the Calvin Cycle?

• Oxygen

• Glucose

• ATP

• NADPH

Which of the following is NOT a product of the light reactions?

• ATP

• NADPH

• Oxygen

• Glucose

What is the role of ATP and NADPH in photosynthesis?

• They are used to capture light energy

• They are used in the Calvin Cycle to produce glucose

• They are waste products of photosynthesis

• They are used to transport water
