Role of leaf in photosynthesis

Stomata present on the leaf which is helps in gaseous exchange at the time of photosynthesis.
stomata-the tiny pores present on the surface of the leaves surrounded by two kidney shaped guard cells are called stomata. Guard cells regulate the opening and closing of stomata.
Functions of stomata-
1.Carbon di oxide from air is taken in and
Oxygen is released through stomata.
2.Transpiration takes place through


Synthesis of food other than carbohydrates

-Plant synthesize carbohydrates through the process of photosynthesis.
-The carbohydrates are made of carbon, hydrogen and oxygen.
-Some times these simplest forms of carbohydrate are utilized to synthesize other nutrients like fats(oil),proteins.
-Some times the starch or glucose is stored in the form of oil in their seed(oil seed). Eg . sunflower
-When the plant nutrient contains,carbon,hydrogen,and oxygen along with nitrogen elements, it is called protein.
 therefore, plants also make fats and proteins as their food other than carbohydrates.
