Photosynthesis and cellular respiration review

What happens during photosynthesis?

• The cell uses energy from sunlight to convert carbon dioxide and water into glucose and oxygen.

• The cell absorbs nutrients from the soil to produce energy.

• The cell releases carbon dioxide and absorbs oxygen during the process.

• The cell converts glucose into carbon dioxide and water using sunlight.

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs without oxygen, while anaerobic respiration requires oxygen.

• Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

• Aerobic respiration is faster than anaerobic respiration.

• Aerobic respiration produces less energy than anaerobic respiration.

What is the significance of oxygen produced during photosynthesis?

• It is used in cellular respiration by most living organisms.

• It is a waste product with no significance.

• It helps in the process of photosynthesis itself.

• It is used to produce glucose directly.

What is the role of chloroplasts in photosynthesis?

• Chloroplasts are the organelles in plant cells where photosynthesis takes place.

• Chloroplasts are responsible for cellular respiration in plants.

• Chloroplasts store nutrients for the plant.

• Chloroplasts help in the absorption of water from the soil.

What captures the sunlight used in photosynthesis?

• Chlorophyll

• Carotene

• Xanthophyll

• Anthocyanin

What is cellular respiration?

• Cellular respiration is the process that cells use to take energy from glucose.

• Cellular respiration is the process of converting sunlight into chemical energy.

• Cellular respiration is the breakdown of proteins into amino acids.

• Cellular respiration is the method by which cells divide and reproduce.

What are the waste products of cellular respiration?

• Oxygen and glucose

• Water and carbon dioxide

• Nitrogen and ammonia

• Lactic acid and ethanol

How do plants obtain carbon dioxide for photosynthesis?

• Through their roots from the soil

• From the air through small openings called stomata

• By absorbing it from water

• Through photosynthesis itself

What factors can affect the rate of photosynthesis?

• Light intensity, carbon dioxide concentration, and temperature.

• Soil pH, humidity, and wind speed.

• Nutrient availability, soil type, and rainfall.

• Plant age, root depth, and leaf size.

What is the role of sunlight in photosynthesis?

• Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose.

• Sunlight is used to cool the plant during the night.

• Sunlight helps in the absorption of nutrients from the soil.

• Sunlight is not necessary for photosynthesis to occur.
