ULTRA STRUCTURE OF PLANT CELLS AND ORGANS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A plant leaf is an organ. In what way is a human lung similar to a plant leaf?
A
Both organs make chemical energy.
B
Both organs are made up of only one kind of cell.
C
Both organs are made up of only one type of protective dermal tissue.
D
Both organs are responsible for the exchange of oxygen and carbon dioxide gases.
Explanation: 

Detailed explanation-1: -Scientists have discovered how plants create networks of air channels–the lungs of the leaf–to transport carbon dioxide (CO2) to their cells. Botanists have known since the 19th century that leaves have pores–called stomata–and contain an intricate internal network of air channels.

Detailed explanation-2: -Okay so this the correct answer for the question is that the human lung and plant leaf, they are similar because both organs exchange oxygen and carbon dioxide exchange oxygen and carbon dioxide.

Detailed explanation-3: -During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Detailed explanation-4: -In a way, they are a cycle-plants help humans breathe by providing us with oxygen, and humans help plants “breathe” by providing them with carbon dioxide.
