Unlike animals, plants are able to obtain ATP through two processes. What are the two processes? Now consider deciduous trees, which drop their leaves in the fall. Do deciduous trees continue to use both these processes during the winter? If not, how do
they stay alive during the winter until they grow new leaves in the spring?
What will be an ideal response?
Plants obtain ATP through cellular respiration as well as photosynthesis. Deciduous trees are unable to conduct photosynthesis after they lose their leaves in the fall. However, deciduous trees can continue to obtain ATP through cellular respiration. This provides the ATP they need for cellular processes during the winter. When the trees grow new leaves in the spring, they can resume photosynthesis.
