Photosynthesis and Cellular Respiration

What is photosynthesis?

• The process by which plants convert sunlight into heat energy.

• The process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

• The method by which animals produce energy from food.

• The way in which soil absorbs nutrients from the atmosphere.

How do photosynthesis and cellular respiration relate to each other?

• Photosynthesis produces glucose and oxygen, which are used in cellular respiration, while cellular respiration produces carbon dioxide and water, which are used in photosynthesis.

• Photosynthesis and cellular respiration are completely independent processes with no relation to each other.

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

• Photosynthesis and cellular respiration are interconnected processes; the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and vice versa.

What is the significance of cellular respiration for living organisms?

• Cellular respiration is essential for living organisms as it provides the energy needed for various cellular processes.

• Cellular respiration is a process that occurs only in plants to produce oxygen.

• Cellular respiration is the method by which organisms reproduce.

• Cellular respiration is a way for organisms to store energy for future use.

What are the main products of cellular respiration?

• Oxygen, glucose, and energy (ATP)

• Carbon dioxide, water, and energy (ATP)

• Nitrogen, water, and energy (ATP)

• Carbon monoxide, glucose, and energy (ATP)

What is cellular respiration?

• A process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water.

• A method of photosynthesis in plants.

• A way for cells to reproduce and divide.

• A technique for storing energy in fat cells.

What happens to carbon dioxide during photosynthesis?

• It is released into the atmosphere as a waste product.

• It is taken in by plants and used to produce glucose.

• It is converted into oxygen and water.

• It is stored in the soil for later use.

What is the equation for photosynthesis?

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

• 6O2 + C6H12O6 → 6CO2 + 6H2O + light energy

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 6H2O + 6CO2 → C6H12O6 + 6O2 + light energy

Can photosynthesis occur at night?

• Yes, it can occur at any time of the day.

• No, photosynthesis requires light, so it primarily occurs during the day.

• Only in the presence of artificial light.

• Yes, but only in certain plants.

Can cellular respiration occur in the absence of oxygen?

• No, it cannot occur without oxygen.

• Yes, it can occur without oxygen through anaerobic respiration.

• Only in plants during photosynthesis.

• Only in certain bacteria under extreme conditions.

What are the main products of photosynthesis?

• Glucose and oxygen

• Carbon dioxide and water

• Nitrogen and glucose

• Oxygen and nitrogen
