Energy Transformation in Photosynthesis

What is the primary function of photosynthesis?

• To provide energy for cellular respiration.

• The primary function of photosynthesis is to convert light energy into chemical energy in the form of glucose.

• To absorb carbon dioxide from the atmosphere.

• To release oxygen as a waste product.

Which organelle is responsible for photosynthesis in plant cells?

• Ribosomes

• Mitochondria

• Nucleus

• Chloroplasts

What are the two main stages of photosynthesis?

• Light absorption and energy storage

• Photosynthesis and respiration

• Light-dependent reactions and light-independent reactions (Calvin cycle)

• Chlorophyll activation and oxygen release

What is the role of chlorophyll in photosynthesis?

• Chlorophyll releases oxygen during photosynthesis.

• Chlorophyll absorbs light energy for photosynthesis.

• Chlorophyll is responsible for water absorption.

• Chlorophyll converts carbon dioxide into glucose.

What are the inputs required for the photosynthesis process?

• Carbon monoxide, water, and soil

• Sunlight, nitrogen, and minerals

• Sunlight, carbon dioxide, and water

• Oxygen, nitrogen, and glucose

What are the main products of photosynthesis?

• Oxygen and carbon monoxide

• Nitrogen and glucose

• Carbon dioxide and water

• Glucose and oxygen

How does light energy get converted during photosynthesis?

• Light energy is transformed into sound energy during photosynthesis.

• Light energy is converted into thermal energy during photosynthesis.

• Light energy is stored as kinetic energy in plant cells.

• Light energy is converted into chemical energy in the form of glucose during photosynthesis.

What is the significance of the Calvin cycle in photosynthesis?

• The Calvin cycle converts glucose into carbon dioxide for respiration.

• The Calvin cycle produces oxygen as a byproduct of photosynthesis.

• The Calvin cycle is significant because it converts carbon dioxide into glucose, providing energy for plants.

• The Calvin cycle is responsible for absorbing sunlight during photosynthesis.

How do environmental factors affect the rate of photosynthesis?

• Photosynthesis only occurs in the presence of soil nutrients.

• Photosynthesis is unaffected by environmental factors.

• Higher temperatures always increase the rate of photosynthesis.

• Environmental factors such as light intensity, carbon dioxide concentration, temperature, and water availability significantly affect the rate of photosynthesis.

What is the relationship between photosynthesis and cellular respiration?

• Cellular respiration produces glucose and oxygen, which are used in photosynthesis.

• Photosynthesis and cellular respiration are unrelated processes that do not affect each other.

• Photosynthesis occurs only at night while cellular respiration happens during the day.

• Photosynthesis produces glucose and oxygen, which are used in cellular respiration to generate energy.
