Why it is necessary for green plants to carry out both photosynthesis and respiration? Select all the correct reasons:

A) Cell respiration utilizes glucose as a fuel to carry out other life processes, such as the transport of materials, cell reproduction, and growth
B) Photosyntheis provides outside energy which is an energy source for the plant as it carries out cell respiration.
C) Cell respiration utilizes alternative sources for fuel to carry out other life processes, such as the transport of materials, cell reproduction, and growth
D) Because plants perform both cellular respiration and photosynthesis during the day.
E) Cellular respiration occurs during the night due to the lack of availability of light.
F) Photosyntheis provides the glucose which is an energy source for the plant as it carries out cell respiration.
