Photosynthesis PPT

Open Ended

Explain why cells need energy and how they obtain it, using examples from both animal and plant cells.

Multiple Choice

What is the main difference between producers and consumers?

• Producers can make their own food, while consumers must eat other organisms to gain energy.

• Producers consume other organisms, while consumers make their own food.

• Producers and consumers both make their own food.

• Producers do not need energy, while consumers do.

Multiple Select

Which of the following are required for photosynthesis to occur?

• Sunlight

• Water

• Oxygen

• Carbon dioxide

Open Ended

Describe the chemical process of photosynthesis and explain why it is important for life on Earth.

Multiple Choice

Which of the following are the products of photosynthesis?

• Glucose and oxygen

• Carbon dioxide and water

• Sunlight and minerals

• Oxygen and carbon dioxide

Open Ended

Explain the difference between light-dependent and light-independent reactions in photosynthesis.

Multiple Choice

What is released as a waste product during the light-dependent reactions of photosynthesis?

• Oxygen

• Carbon dioxide

• Glucose

• Water

Multiple Select

Which of the following statements about the light-dependent reaction are correct?

• It captures energy from the sun.

• It occurs in the grana of the chloroplast.

• It produces glucose directly.

• It stores energy in ATP and NADPH.

Open Ended

Describe the role of the Electron Transport Chain in the light-dependent reactions of photosynthesis.

Multiple Choice

Which pigment is responsible for absorbing sunlight in photosystems?

• Chlorophyll

• Carotene

• Xanthophyll

• Anthocyanin

Multiple Select

Which of the following are products of the light-dependent reactions of photosynthesis?

• ATP

• NADPH

• Oxygen

• Glucose

Open Ended

Explain the role of ATP and NADPH in the light-dependent reactions of photosynthesis.

Multiple Choice

Where does the light-independent reaction (Calvin Cycle) occur in the chloroplast?

• Stroma

• Thylakoid membrane

• Grana

• Outer membrane

Open Ended

Describe the process by which carbon dioxide is incorporated into the Calvin Cycle and what happens to it during the cycle.

Multiple Choice

What is the main purpose of the Calvin Cycle in the light-independent reactions of photosynthesis?

• To produce glucose from carbon dioxide

• To split water molecules and release oxygen

• To absorb sunlight and generate ATP

• To convert glucose into ATP

Open Ended

Explain how the light-independent reactions and light-dependent reactions are connected in the process of photosynthesis.

Multiple Select

Which of the following are products of the light-independent reactions (Calvin Cycle)?

• Glucose

• NADP+

• ADP

• Oxygen

Multiple Choice

Which factor does NOT directly affect the rate of photosynthesis?

• Amount of oxygen

• Light intensity

• Amount of CO2

• Temperature

Multiple Choice

Why do root cells in a plant NOT need chloroplasts?

• They are not exposed to sunlight

• They store water

• They absorb minerals

• They produce glucose
