Exploring the Process of Photosynthesis

What are the essential supplies needed for photosynthesis?

• Oxygen, water, and sunlight

• Carbon dioxide, water, and sunlight

• Carbon dioxide, oxygen, and sunlight

• Glucose, water, and sunlight

Through which part of the plant does carbon dioxide enter?

• Flowers

• Roots

• Stem

• Pores of the leaf

Where in the plant cell does photosynthesis occur?

• Chloroplast

• Nucleus

• Ribosome

• Mitochondria

What is the function of the thylakoid in the chloroplast?

• Stores glucose

• Produces ATP

• Releases oxygen

• Contains chlorophyll

What happens to water molecules during the light-dependent reactions?

• They are converted into glucose

• They are split into oxygen and hydrogen ions

• They are absorbed by the roots

• They are stored in the vacuole

What is produced by the electron transport chain during photosynthesis?

• Carbon dioxide and water

• NADPH and ATP

• Chlorophyll and sunlight

• Glucose and oxygen

What is the main purpose of the Calvin cycle?

• To convert carbon dioxide into glucose

• To split water molecules

• To produce NADPH and ATP

• To release oxygen into the atmosphere

Which molecules are used in the Calvin cycle to produce glucose?

• Oxygen and water

• Carbon dioxide and hydrogen

• NADPH and ATP

• Chlorophyll and sunlight

What are the reactants in the photosynthesis chemical equation?

• NADPH and ATP

• Carbon dioxide and water

• Chlorophyll and sunlight

• Glucose and oxygen

Why is photosynthesis considered an endothermic reaction?

• It releases oxygen into the atmosphere

• It produces energy in the form of ATP

• It absorbs energy from the sun

• It releases energy in the form of heat
