In the cells of every living being, it is important to maintain adequate energy levels in accordance with its requirements. To keep our body in balance, humans can take care of their diets and do physical activity. On the other hand, plants transform energy from sunlight into chemical energy and sugars thanks to photosynthesis. Two of the most important sugars for plants are starch and sucrose, from which they obtain the energy they need for an adequate development. In addition to being autotrophic, plants are also immobile organisms, so how can a plant cell regulate their energy levels? In this article we will describe how some sugars play a role beyond providing energy, as they can also indicate the cell how to keep balance, thus regulating plant growth.
