What is the food manufacturing process in plants called?

Plants make food by a process known as photosynthesis. As the name suggests, photo or light energy is used in this process of synthesis. Plants use three ingredients: sun light, carbon dioxide (CO2) and water (H2O) to make food (sugars). The following takes place during photosynthesis:

6CO_2 + 6H_2O + (light) -> C_6H_(12)O_6 + 6)_2

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
