Shouldn’t respiration take place in plants to obtain energy? Yes, respiration takes place in plants too. All living beings use oxygen for respiration. As a result, carbon dioxide is produced. Animals release carbon dioxide. Carbon dioxide produced as a result of respiration by plants is used for photosynthesis during day time. Carbon dioxide from the atmosphere is also used by plants for photosynthesis. Air enters plants through the leaves. Let us examine whether there is any special part in the leaves for this. Observe the leaf layer in a microscope and draw it in the science diary.
Stomata Illustration 1.10 A microscope is an instrument used to magnify things that cannot be seen with the naked eyes. These microscopic pores in the leaves are known as stomata. It is through these pores atmospheric air enters the plant. Oxygen produced as a result of photosynthesis is also released through these pores. Basic Science V 21
