Plants perform photosynthesis to create their own food source and use cellular respiration to unlock the energy from that food.
In 3-5 sentences, argue which one of these two processes is used at certain times of day by plants. Specifically, which process is used during bright
daylight hours, which process is used at night, and which process is used during early morning and late evening low-light hours? Why do you
think this is the case? (4 points)
photosynthesis requires sun to produce energy while cellular respiration does not. photosynthesis begins in the morning when the sun rises and slows down as the sun goes down. cellular respiration starts when the sun is going down and continues all night until the sun starts rising.
