Why are scientists researching photosynthesis?

• To understand plant evolution

• To develop new types of fertilizers

• To improve crop success and fight world hunger

• To discover new plant species

Which statement accurately describes how photosynthetic organisms handle energy?

• They create energy from sunlight.

• They transform energy from non-living sources into a usable form.

• They consume energy from other organisms.

• They destroy energy to produce food.

What are the primary molecular inputs required for photosynthesis to produce glucose and oxygen?

• Glucose and Oxygen

• Carbon Dioxide and Water

• Sunlight and ATP

• Proteins and Lipids

How do photosynthesis and cellular respiration relate to each other in terms of inputs and outputs?

• They are identical processes.

• They are unrelated processes.

• They are complementary processes with opposite inputs and outputs.

• Photosynthesis only occurs in plants, while cellular respiration only occurs in animals.

• Oxygen

• ATP

What two energy-carrying molecules are produced during the light-dependent reactions of photosynthesis?

• ATP and ADP

• NADPH and NADP+

• ATP and NADPH

• Glucose and Oxygen

In which part of the chloroplast do the light-independent reactions (Calvin Cycle) occur?

• Thylakoid membrane

• Stroma

• Outer membrane
