None of the above

Detailed explanation-1: -Respiration occurs in the presence of oxygen to form water and carbon dioxide to breakdown glucose and release energy. Respiration does not require sunlight and chlorophyll, photosynthesis requires these. Therefore this statement is false.
Detailed explanation-2: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
Detailed explanation-3: -Cellular respiration and photosynthesis are direct opposite reactions. Energy from the sun enters a plant and is converted into glucose during photosynthesis. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat.
Detailed explanation-4: -Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
Detailed explanation-5: -The correct option is B False. Photosynthesis & Respiration in plants: Plants breathe at all times of the day and night. Photosynthesis and respiration occur throughout the day, whereas only respiration and dark processes occur at night.
