Of course they do... Remember that plant cells also contain a or mitochondrion. Photosynthesis requires ATP to start the reaction for Glucose production. So plants go through cellular respiration to produce ATP. Remember that plants during the winter lose there leaves, and photosynthesis occurs in the leaves. Where does the energy come from to keep the plant alive during the winter? The answer would be cellular respiration. Plants use photosynthesis to produce energy, not to use energy. Energy from photosynthesis is used as a means of storage. Like fat in humans. However when the energy levels are low then stored energy is used. So plants go through cellular respiration.
