Explanation:
Detailed explanation-1: -In most plants, photosynthesis occurs in special cells known as chloroplasts. The green hue we see in plants is the result of tiny grains of green pigment (light-absorbing molecules) inside the chloroplasts. These pigments are commonly known as chlorophyll (chloro=green; phyll=leaf).
Detailed explanation-2: -The alveoli are the sites of gas exchange; they are located at the terminal regions of the lung and are attached to the respiratory bronchioles. The acinus is the structure in the lung where gas exchange occurs. The sac-like structure of the alveoli increases their surface area.
