This episode explains how plants utilise glucose created during photosynthesis. 

A major use of glucose is for respiration, providing the energy a plant needs. Glucose can also be transformed into starch for energy storage, particularly in roots, stems and leaves. 

Furthermore, it is converted into cellulose to strengthen cell walls, a process vital for rapidly growing plants. 

We also note the conversion of glucose into fats, oils and proteins, all essential for development and repair; for the final transformation, a nitrogen source from the soil is required.
