Detailed explanation-1: -The correct answer is false. This is because plants perform both photosynthesis and cellular respiration. The process of photosynthesis requires carbon dioxide, water, and sunlight. Photosynthesis is necessary in order to produce food for the plant.

Detailed explanation-2: -Respiration is essential for growth and maintenance of all plant tissues, and plays an important role in the carbon balance of individual cells, whole-plants and ecosystems, as well as in the global carbon cycle.

Detailed explanation-3: -Complete answer: Photosynthesis and respiration take place all the time in plants: This statement is not entirely true. Although respiration in plants occurs all the time, photosynthesis only occurs in the presence of sunlight.

Detailed explanation-4: -The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.
